== Function ==
[https://www.uniprot.org/uniprot/SUBC_BACLI SUBC_BACLI] Subtilisin is an extracellular alkaline serine protease, it catalyzes the hydrolysis of proteins and peptide amides (Ref.4, PubMed:11109488). Shows high specificity for aromatic and hydrophobic amino acids in the P1 substrate position (PubMed:11109488). May play an important role in the degradation of feather keratin (PubMed:11109488).<ref>PMID:11109488</ref> <ref>PMID:4967581</ref>

==Overview==
<references/>
The crystal structure of subtilisin Carlsberg lightly cross-linked with glutaraldehyde was solved in aqueous solution by X-ray crystallography at 2.3 A resolution. It was found to be virtually identical to the recently determined (Fitzpatrick, P.A., Steinmetz, A.C.U., Ringe, D.A. &amp; Klibanov, A.M. (1993) Proc. Natl. Acad. Sci. USA 90, 8653) structure of the cross-linked enzyme in anhydrous acetonitrile. The latter structure was found to be significantly more rigid than in water, as reflected by their average B factors. The numbers of subtilisin-bound water molecules in the two structures are similar (114 and 99 in water and in acetonitrile, respectively), but the locations of some half of these bound waters are distinct.
