Cleaves host elastin, collagen, IgG, and several complement components as well as endogenous pro-aminopeptidase. Autocatalyses processing of its pro-peptide. Processes the pro-peptide of pro-chitin-binding protein (cbpD). Involved in the pathogenesis of P.aeruginosa infections. Elastase Protein, Pseudomonas aeruginosa, Recombinant (His & SUMO) is expressed in E. coli expression system with N-6xHis-SUMO tag. The predicted molecular weight is 49.1 kDa and the accession number is P14756.
