    ABSTRACT: Isoamylase catalyzes the hydrolysis of α-1,6-glycosidic linkages in glycogen, amylopectin and α/β-limit dextrins. A semi-rational design strategy was performed to improve catalytic properties of isoamylase from Bacillus lentus. Three residues in vicinity of the essential residues, Arg505, Asn513, and Gly608, were chosen as the mutation sites and were substituted by Ala, Pro, Glu, and Lys, respectively. Thermal stability of the mutant R505P and acidic stability of the mutant R505E were enhanced. The k cat /K m values of the mutant G608V have been promoted by 49 %, and the specific activity increased by 33 %. This work provides an effective strategy for improving the catalytic activity and stability of isoamylase, and the results obtained here may be useful for the improvement of catalytic properties of other α/β barrel enzymes.

    ABSTRACT: Tuberculosis (TB) is a serious and potentially fatal disease caused by Mycobacterium tuberculosis (M. tb). The occurrence of multidrug-resistant (MDR) and extensively drug-resistant (XDR) M. tb is a significant public health concern because most of the anti-TB drugs that have been in use for over 40 years are no longer effective for the treatment of these infections. Recently, new anti-TB lead compounds such as cyclomarin A, lassomycin, and ecumicin, which are cyclic peptides from actinomycetes, have shown potent anti-TB activity against MDR and XDR M. tb as well as drug-susceptible M. tb in vitro. The target molecule of these antibiotics is ClpC1, a protein that is essential for the growth of M. tb. In this review, we introduce the three anti-TB lead compounds as potential anti-TB therapeutic agents targeting ClpC1 and compare them with the existing anti-TB drugs approved by the US Food and Drug Administration.

    ABSTRACT: Bacterial natural products have proven to be invaluable starting points in the development of many currently used therapeutic agents. Unfortunately, traditional culture-based methods for natural product discovery have been deemphasized by pharmaceutical companies due in large part to high rediscovery rates. Culture-independent, or "metagenomic," methods, which rely on the heterologous expression of DNA extracted directly from environmental samples (eDNA), have the potential to provide access to metabolites encoded by a large fraction of the earth's microbial biosynthetic diversity. As soil is both ubiquitous and rich in bacterial diversity, it is an appealing starting point for culture-independent natural product discovery efforts. This review provides an overview of the history of soil metagenome-driven natural product discovery studies and elaborates on the recent development of new tools for sequence-based, high-throughput profiling of environmental samples used in discovering novel natural product biosynthetic gene clusters. We conclude with several examples of these new tools being employed to facilitate the recovery of novel secondary metabolite encoding gene clusters from soil metagenomes and the subsequent heterologous expression of these clusters to produce bioactive small molecules.

    ABSTRACT: The role of secondary metabolites in effecting and modulating reactions during early biochemical evolution has been largely unappreciated. It is possible that low molecular weight effectors were gradually replaced by polypeptides as polymerizing reactions became more complex, but retained some ability to interact with original receptor sites. Indeed, by reviewing the era of antibiotics in this light we can begin to reconcile the ancient and contemporary activities of these molecules. The corollary being that secondary metabolites participate in a vast array of interactions in nature and investigating their intended receptors will be revealing in both pharmacological and evolutionary terms.

    ABSTRACT: Glutathione (GSH) is an important bioactive substance applied widely in pharmaceutical and food industries. Due to the strong product inhibition in the GSH biosynthetic pathway, high levels of intracellular content, yield and productivity of GSH are difficult to achieve. Recently, a novel bifunctional GSH synthetase was identified to be less sensitive to GSH. A recombinant Escherichia coli strain expressing gshF encoding the bifunctional glutathione synthetase of Streptococcus thermophilus was constructed for GSH production. In this study, efficient GSH production using this engineered strain was investigated. The cultivation process was optimized by controlling dissolved oxygen (DO), amino acid addition and glucose feeding. 36.8 mM (11.3 g/L) GSH were formed at a productivity of 2.06 mM/h when the amino acid precursors (75 mM each) were added and glucose was supplied as the sole carbon and energy source.

    ABSTRACT: The Saccharomyces cerevisiae HAP4 gene encodes a transcription activator that plays a key role in controlling the expression of genes involved in mitochondrial respiration and reductive pathways. This work examines the effect of knockout of the HAP4 gene on aerobic ethanol production in a xylose-utilizing S. cerevisiae strain. A hap4-deleted recombinant yeast strain (B42-DHAP4) showed increased maximum concentration, production rate, and yield of ethanol compared with the reference strain MA-B42, irrespective of cultivation medium (glucose, xylose, or glucose/xylose mixtures). Notably, B42-DHAP4 was capable of producing ethanol from xylose as the sole carbon source under aerobic conditions, whereas no ethanol was produced by MA-B42. Moreover, the rate of ethanol production and ethanol yield (0.44 g/g) from the detoxified hydrolysate of wood chips was markedly improved in B42-DHAP4 compared to MA-B42. Thus, the results of this study support the view that deleting HAP4 in xylose-utilizing S. cerevisiae strains represents a useful strategy in ethanol production processes.

    ABSTRACT: Technological improvements have accelerated natural product (NP) discovery and engineering to the point that systematic genome mining for new molecules is on the horizon. NP biosynthetic potential is not equally distributed across organisms, environments, or microbial life histories, but instead is enriched in a number of prolific clades. Also, NPs are not equally abundant in nature; some are quite common and others markedly rare. Armed with this knowledge, random 'fishing expeditions' for new NPs are increasingly harder to justify. Understanding the ecological and evolutionary pressures that drive the non-uniform distribution of NP biosynthesis provides a rational framework for the targeted isolation of strains enriched in new NP potential. Additionally, ecological theory leads to testable hypotheses regarding the roles of NPs in shaping ecosystems. Here we review several recent strain prioritization practices and discuss the ecological and evolutionary underpinnings for each. Finally, we offer perspectives on leveraging microbial ecology and evolutionary biology for future NP discovery.

    ABSTRACT: FK506, a 23-membered macrolide produced by several Streptomyces species, is an immunosuppressant widely used to prevent the rejection of transplanted organs. In addition, FK506 and its analogs possess numerous promising therapeutic potentials including antifungal, neuroprotective, and neuroregenerative activities. Herein, we introduce the biological activities and mechanisms of action of FK506 and discuss recent progress made in understanding its biosynthetic pathway, improving production, and in the mutasynthesis of diverse analogs. Perspectives highlighting further strain improvement and structural diversification aimed at generating more analogs with improved pharmaceutical properties will be emphasized.

    ABSTRACT: Establishment of novel metabolic pathways for biosynthesis of chemicals, fuels and pharmaceuticals has been demonstrated in Escherichia coli due to its ease of genetic manipulation and adaptability to varying oxygen levels. E. coli growing under microaerobic condition is known to exhibit features of both aerobic and anaerobic metabolism. In this work, we attempt to engineer this metabolism for production of 1,2-propanediol. We first redirect the carbon flux by disrupting carbon-competing pathways to increase the production of 1,2-propanediol microaerobically from 0.25 to 0.85 g/L. We then disrupt the first committed step of E. coli's ubiquinone biosynthesis pathway (ubiC) to prevent the oxidation of NADH in microaerobic conditions. Coupling this strategy with carbon flux redirection leads to enhanced production of 1,2-propanediol at 1.2 g/L. This work demonstrates the production of non-native reduced chemicals in E. coli by engineering its microaerobic metabolism.

    ABSTRACT: The co-culture system of the fermentation process of vitamin C can be regarded as an artificial microbial ecosystem (AME). To extend our understanding of this AME, an investigation of the relationship between strains, substrate and product was carried out in this study. The results showed that both Ketogulonicigenium vulgare and 2-keto-l-gulonic acid (2-KLG, the precursor of vitamin C) can inhibit the growth of the helper strain, while the helper strain promoted the growth of K. vulgare and 2-KLG production. Moreover, l-sorbose is not only a substrate for 2-KLG production in the AME, but also a promoter of K. vulgare and an inhibitor of the helper strain. In the earlier stage of fermentation, the inhibition of l-sorbose on the helper strain's growth is a key factor for ensuring an efficient fermentation. In the condition of adding the extra helper strain (OD: 0.57, ratio of inoculation: 2 %), the yields of 2-KLG is increased by 9 % in the 14 % l-sorbose medium. To the best of our knowledge, this is the first report about the inhibition of substrate in the AME of 2-KLG production.

    ABSTRACT: Rapamycin is an important natural macrolide antibiotic with antifungal, immunosuppressive and anticancer activity produced by Streptomyces hygroscopicus. In this study, a mutant strain obtained by ultraviolet mutagenesis displayed higher rapamycin production capacity compared to the wild-type S. hygroscopicus ATCC 29253. To gain insights into the mechanism of rapamycin overproduction, comparative metabolic profiling between the wild-type and mutant strain was performed. A total of 86 metabolites were identified by gas chromatography-mass spectrometry. Pattern recognition methods, including principal component analysis, partial least squares and partial least squares discriminant analysis, were employed to determine the key biomarkers. The results showed that 22 potential biomarkers were closely associated with the increase of rapamycin production and the tremendous metabolic difference was observed between the two strains. Furthermore, metabolic pathway analysis revealed that amino acids metabolism played an important role in the synthesis of rapamycin, especially lysine, valine, tryptophan, isoleucine, glutamate, arginine and ornithine. The inadequate supply of amino acids, or namely "nitrogen starvation" occurred in the mutant strain. Subsequently, the exogenous addition of amino acids into the fermentation medium of the mutant strain confirmed the above conclusion, and rapamycin production of the mutant strain increased to 426.7 mg/L after adding lysine, approximately 5.8-fold of that in the wild-type strain. Finally, the results of real-time PCR and enzyme activity assays demonstrated that dihydrodipicolinate synthase involved with lysine metabolism played vital role in the biosynthesis of rapamycin. These findings will provide a theoretical basis for further improving production of rapamycin.
