Beschreibung

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 is a zinc metalloprotein that catalyzes the kinetic resolution of unnatural and rarely occurring α-amino acids. Its enantioselectivity for the hydrolysis of N-acyl L-α-amino acids is nearly absolute, yet it accepts substrates having a wide range of structure and functionality. 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.

Analysis Note

Protein determined by biuret.

Other Notes

One unit will hydrolyze 1.0 μmole of N-acetyl-L-methionine per hr at pH 7.0 at 25 °C.
