| + | == 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> | ||

| + | == Publication Abstract from PubMed == | ||
| + | The X-ray crystal structures of the protease subtilisin Carlsberg in 40% acetonitrile and in 20% dioxane have been determined to at least 2.3 A resolution, and their solvent binding patterns have been compared to those observed in the neat organic solvents. The structures of the protein in the two aqueous-organic mixtures are essentially the same as in pure water, acetonitrile, and dioxane. Interestingly, the enzyme-bound organic solvent molecules tend to congregate in the active site. Three of the five bound acetonitrile molecules observed in the structure of subtilisin in 40% acetonitrile are situated in the enzyme active site, as is the single enzyme-bound dioxane molecule observed in 20% dioxane (whose location is distinct from that of any bound acetonitrile molecule). Furthermore, the organic solvent molecules detected in the enzyme active site in the aqueous-organic mixtures are in the same locations as in the structures in the corresponding neat organic solvents. | ||
