Acylase I du rein de porcine, Grade I, poudre lyophilisée ,> = 2 000 unités/mg de protéines

Non disponible en dehors du Royaume-Uni et de l'Irlande

Analysis Note

Protein determined by biuret.

Application

Acylase I from porcine kidney has been used to study the acylase I-catalyzed deacetylation of various S-alkyl-N-acetyl-L-cysteines and their carbon and oxygen analogues . Acylase I may be useful to catalyze N-acetyl amino acids to enantiomerically pure L-amino acids .

Biochem/physiol Actions

Acylase I catalyzes the deacetylation of N-acetyl-L-cysteine and S-alkyl-N-acetyl-L-cysteines. n-Butylmalonic acid is an inhibitor of acylase I. S-alkyl-N-acetyl-L-cysteines with short (C0-C3) and unbranched S-alkyl substituents have been found to be good acylase I substrates .
