Cysteine endopeptidases
BRITE hierarchy
Reaction(IUBMB)
Hydrolysis of proteins and small molecule substrates, with a preference for Arg in P1
Comment
A secreted endopeptidase from the bacterium Porphyromonas gingivalis. Strongly activated by glycine [1], and stabilized by Ca2+. Precursor molecule contains a hemagglutinin domain [2,3]. Misleadingly described in some literature as "trypsin-like", being a cysteine peptidase, type example of family C25
