Interact With
Induction
Subcellular Location SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:12419815}. Note=Experiments performed in E.coli.
Modified Residue
Post Translational Modification PTM: Experiments performed in E.coli. Processing of pro-endopeptidase to mature endopeptidase is probably autocatalytic, as mutations in the probable active site residues prevent processing, and purified inactive pro-endopeptidase disappears in the presence of active endopeptidase. {ECO:0000305|PubMed:12419815}.
