Activity Regulation | ACTIVITY REGULATION: Calcium plays an important structural role, providing stability to this protein in the cytoplasm. Outside the cell, the decrease of the calcium concentration triggers the autoproteolysis. {ECO:0000250|UniProtKB:Q9KMU6}. |

Enzyme Function | FUNCTION: Metalloprotease that exhibits a cytotoxic effect leading to cell death. In host tissues, it could play a role in pathogenesis by modulating the stability of the extracellular matrix components such as fibronectin and fibrinogen. Also able to cleave plasminogen. {ECO:0000250|UniProtKB:Q9KMU6}. |

Post Translational Modification | PTM: PrtV is expressed as an inactive, multidomain, 102 kDa pre-pro-metalloprotease. To form a catalytically active protease, PrtV is first secreted, and then it undergoes N- and C-terminal cleavages during envelope translocation to yield a 81 kDa pro-metalloprotease. Outside the cell, the 81 kDa pro-metalloprotease undergoes an auto-cleavage. The two major products of autoproteolysis (37 kDa and 18 kDa) together form the so called 55 kDa active complex. {ECO:0000250|UniProtKB:Q9KMU6}. |
