Binds chitin but does not hydrolyze it, has no detectable protease or staphylolytic activity. Secreted in an Xcp-dependent fashion (a type II secretion pathway). Can be detected in the extracellular supernatant as a 43 kDa protein and a 23 kDa protein, both proteins have the same N-terminus (PubMed:9642203, PubMed:10671445). Only the larger protein binds chitin, which may protect it from further processing and/or degradation by elastase (lasB) (PubMed:10671445, PubMed:9642203). It is not clear whether the short form is functional or a degradation product. Decreases chitin-binding, has no visible effect on extracellular staphylolytic or protease activity (PubMed:10671445). Decreased association with the hyphae form of C.albicans strain SC5314; P.aeruginosa does not adhere to yeast form C.albicans (PubMed:23509956). Was originally thought to be a protease that processes pro-LasA.
