Subtilisin 9014-01-1Synonyms: Subtilisin Carlsberg, Subtilopeptidase A, Bacterial Alkaline Protease CAS #: 9014-01-1EC #: 3.4.21.62Sigma's Subtilisins are produced from fermentation of Bacillus licheniformis. We offer several grades and formulations including high purity lyophilized powders as well as economical industrial grade solutions.Physical properties and Specificity:MW: Subtilisin is a non-glycosylated single polypeptide chain without disulfide bonds and a of MW 27 KDa.2Specificity: 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.Isoelectric point: pI = 9.4E1%(280nm) = 8.6Sedimentation coefficient: S20,w = 2.773 Activity Determination and Optimal Conditions:Unit definition: One Sigma Unit will hydrolyze casein to produce color equivalent to 1.0 mmole (181 µg) of tyrosine per minute at pH 7.5 at 37 (color by Folin-Ciocalteu reagent).Usage:1>Proteolytic enzymes. Mainly used in gelatin production can greatly reduce extraction time, also used in vegetable protein, animal protein and fish protein hydrolysis. 2>Bacteria fungicides. On several plant pathogenic fungi had strong antagonism, can effectively prevent the disease of cucumber and tobacco
