The Proteomic Identification of Cleavage Sites (PICS) approach was employed for profiling the substrate specificity of HF3, a hemorrhagic snake venom metalloproteinase (SVMP) from Bothrops jararaca. A tryptic peptide library ...

Both serine and metalloproteinases have been shown to play the role of toxins in the venoms of many snakes. Determination of the natural protein substrates of these toxins is an important feature in the toxinological ...

The cleavage specificity of a monobasic processing dynorphin converting endoprotease is examined with a series of quench fluorescent peptide substrates and compared with the cleavage specificity of prohormone convertases, ...

Peptides from skin secretions of amphibians are considered important components of their immune system and also play a relevant role in their defense mechanism against predators. Herein, by using mass spectrometry (MS), ...

The opportunistic bacterium Proteus mirabilis secretes a metalloprotease, ZapA, considered to be one of its virulence factors due to its IgA-degrading activity. However, the substrate specificity of this enzyme has not yet ...

P>Neuropeptides are produced from larger precursors by limited proteolysis, first by endopeptidases and then by carboxypeptidases. Major endopeptidases required for these cleavages include prohormone convertase (PC) 1/3 ...

CD4+ T cells have a major role in regulating immune responses. They are activated by recognition of peptides mostly generated from exogenous antigens through the major histocompatibility complex (MHC) class II pathway. ...
