Amino acid analysis and isoelectric focusing electrophoresis consistent with subtilisin Carlsberg.
Subtilisin A is a member of the Serine S8 Endoproteinase family. It has broad specificity with a preference for a large uncharged residue in the P1 position. It hydrolyzes native and denatured proteins, and is active under alkaline conditions.
One unit will hydrolyze casein to produce color equivalent to 1.0 μmole (181 μg) of tyrosine per min at pH 7.5 at 37 °C (color by Folin-Ciocalteu reagent).
This is a proteolytic enzyme isolated from the fermentation of Bacillus licheniformis. It is a serine endoproteinase with a broad specificity towards native and denatured proteins, and is active under alkaline conditions. Product P8038, also known as Subtilisin Carlsberg, has been used to hydrolyze cardiac cells to study the silencing of cardiac mitochondrial NHE11.
Proteinase catabolizes proteins by hydrolysis of peptide bonds. Proteases are inactivated by serine active-site inhibitors, such as phenylmethylsulfonyl fluoride (PMSF) and diisopropylfluorophosphat
Subtilisin is a non-glycosylated single polypeptide chain without disulfide bonds and has a molecular weight of 27 KDa.
