Secondry Information

Protein Function enzyme that selectively catalyzes the release of the carboxyl-terminal basic amino acids, arginine and lysine, from proteins and peptides; possess esterase activity toward hippuryl-n-argininic acid
Biochemical Properties The inhibition of the enzyme by phosphate and that by citrate are pH-dependent and are most pronounced below pH 6.5; decreasing effectiveness as inhibitors at pH 8: NaI, KSCN, NaBr, MgS04, NaCI, KCl, and NaN03;
Significance in milk belong to the protease system in milk
