Involved in proteolysis and elastolysis (degradation of the host protein elastin). Has staphylolytic activity (degrades pentaglycine cross-links in cell wall peptidogylcan), preferring Gly-Gly-|-X substrates where X is Ala or Gly. Enhances the elastolytic but not proteolytic activity of elastase (lasB) and elastolytic activity of other proteases. Degradation of host elastin is likely to contribute to the pathogenicity of P.aeruginosa. While either His-317 or His-356 can abstract a proton in the hydrolysis reaction, the same residue performs both functions in a given catalytic cycle, with the other stabilizing the catalytic intermediate.

crystal structures of active LasA as a complex with tartrate and in the uncomplexed form. While the overall fold resembles that of the other M23 family members, the LasA active site is less constricted and utilizes a different set of metal ligands. PMID: 20026068
Data suggest that these clustered residues in the propeptide may play an important role in promoting the correct protein conformation of the mature LasA protease domain. PMID: 17351039
These data show that SP-D can contribute to the clearance of P. aeruginosa from the healthy ocular surface and that proteases can compromise that clearance. PMID: 19349424
