| catalytic Activity | CATALYTIC ACTIVITY: Reaction=Hydrolysis of proteins and small molecule substrates, with a preference for Arg in P1.; EC=3.4.22.37; Evidence={ECO:0000250|UniProtKB:P95493}; |
| DNA Binding | |
| EC Number | 3.4.22.37 |
| Enzyme Function | FUNCTION: Thiol protease. Acts synergistically with RgpA to catalyze the maturation of fimbrial subunits, such as FimA (PubMed:9786913). Its proteolytic activity is a major factor in both periodontal tissue destruction and in evasion of host defense mechanisms (By similarity). {ECO:0000250|UniProtKB:P95493, ECO:0000269|PubMed:9786913}. |
