...Izabela Maluch; Justyna Grzymska; Scott J. Snipas; Guy S. Salvesen; Marcin Drag Caspases are a family of enzymes that play roles in cell death and inflammation. It has been suggested that in the execution phase of the apoptotic pathway, caspase-3, -6 and -7 are involved. The substrate specificities...

...Sheng Chen; Hoi Ying Wan BoNTs (botulinum neurotoxins) are both deadly neurotoxins and natural toxins that are widely used in protein therapies to treat numerous neurological disorders of dystonia and spinal spasticity. Understanding the mechanism of action and substrate specificity of BoNTs...

... substrates, however, remain unknown. In a yeast two-hybrid screen of a human heart cDNA library with a dominant-negative Mst1 (K59R) mutant used as bait, cTn [cardiac Tn (troponin)] I was identified as an Mst1-interacting protein. The interaction of cTnI with Mst1 was confirmed by co-immunoprecipitation...

... drug targets. To facilitate a rational drug discovery programme, in the current study we analysed the synthetic substrate and model inhibitor profiles of FP-2 and FP-3 as well as BP-2 (berghepain-2), an orthologue from the rodent parasite Plasmodium berghei . With respect to substrate catalysis, FP-2...

... for its specificity for N-acetylated substrates. Based on the comparison of the substrate binding site of WbpP with that of other C4 epimerases that convert preferentially non-acetylated substrates, or that are able to convert both acetylated and non-acetylated substrates equally well, specific residues...
