Enzyme Function | FUNCTION: Secreted protease which is important for P.entomophila to counteract the local immune response of Drosophila (PubMed:16789834). Can degrade antimicrobial peptides (AMPs), e.g. Diptericin and Cecropin A. Thus, protects P.entomophila from the Drosophila antimicrobial peptides produced by the gut innate immune response, and promotes bacterial persistence in the Drosophila gut and killing of the host (PubMed:16789834). Is responsible for maturation of pro-Monalysin to the active toxin Monalysin, by cleaving its N-terminus (PubMed:21980286). {ECO:0000269|PubMed:16789834, ECO:0000269|PubMed:21980286}. |

Interact With | |
Induction | INDUCTION: Is regulated by the GacS/GacA two-component system that controls P.entomophila pathogenicity. Seems also regulated by PrtR. {ECO:0000269|PubMed:16789834}. |
Subcellular Location | SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:16789834, ECO:0000269|PubMed:21980286}. Note=Is probably secreted via the associated Type 1 transporter encoded by aprDEF. {ECO:0000305|PubMed:16789834}. |
