How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

- Biocatalysis and structural biology of Cytochrome P450 Monooxygenases, Oxidases and Unspecific Peroxygenases.
Selective oxyfunctionalization of non-activated C–H bonds remains a major challenge in synthetic chemistry. The biocatalytic hydroxylation of non-activated C–H bonds by cytochrome P450 monooxygenases (CYPs), however, offers catalysis with high regio- and stereoselectivity using molecular oxygen. CYP153s are a class of CYPs known for their selective...
Baeyer-Villiger monooxygenases (BVMOs) are flavin-dependent enzymes that primarily convert ketones to esters, but can also catalyze heteroatom oxidation. Several structural studies have highlighted the importance of the ‘control loop’ in BVMOs, which adopts different conformations during catalysis. Central to the ‘control loop’ is a conserved trypt...
TbFKBP12 is a putative peptidyl prolyl cis–trans isomerase from Trypanosoma brucei, causative agent of the African trypanosomiasis or sleeping sickness. It interacts with the immunosuppressive drug rapamycin inhibiting the formation of TORC2 complex leading to parasite death by inhibiting cell proliferation through cytokinesis blockade. Moreover, R...
A Trypanosoma cruzi cysteine protease inhibitor, termed chagasin, is the first characterized member of a new family of tight-binding cysteine protease inhibitors identified in several lower eukaryotes and prokaryotes but not present in mammals. In the protozoan parasite T.cruzi, chagasin plays a role in parasite differentiation and in mammalian hos...
1H, 15 N and 13C assignments of the cysteine protease inhibitor Chagasin from Trypanosoma cruzi DOI 10.1007/s10858-006-0014-x Chagasin was characterized in T. cruzi (Monteiro et al., 2001) as novel type of tight-binding inhibitor of cruzipain, the major T. cruzi cysteine protease, which belongs to the papain superfamily. It was recently reported th...
WW domains are small protein-protein interaction modules that recognize proline-rich stretches in proteins. The class II tandem WW domains of the formin binding protein 11 (FBP11) recognize specifically proteins containing PPLPp motifs as present in the formins that are involved in limb and kidney development, and in the methyl-CpG-binding protein...
