Studying the metabolic role of non‐essential promiscuous enzymes is a challenging task, as genetic manipulations usually do not reveal at which point(s) of the metabolic network the enzymatic activity of such protein is beneficial for the organism. Each of the HAD‐like phosphatases YcsE, YitU and YwtE of Bacillus subtilis catalyzes the dephosphoryl...
Ecuador is one of the most important producers of fine cocoa. In addition to the fine cocoa type Nacional (Arriba), however, the cheaper but less aromatic bulk cocoa “Colección Castro Naranjal 51” (CCN-51) is also cultivated there. In a previous work, several characteristic SNPs could be identified to distinguish these two varieties. However, the d...
Background:
Little is known about breast milk as a vehicle for tolerance development or sensitization to peanuts very early in life. Thus, well-characterized and highly sensitive detection systems for the reliable determination of peanut allergens in breast milk are mandatory.
Methods:
For the quantification of the marker allergens Ara h 2 and A...
For the routine detection of allergens in foods, PCR and/or ELISA methods are employed. To assess the suitability of these methods, proficiency tests (PTs) could be used as a valuable instrument. It is a common practice to evaluate the results with respect to the experimentally obtained robust mean without considering the actual allergen content. I...
