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 .

Unit Definition

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

Analysis Note

Protein determined by biuret.

PS-5 was deacetylated to NS-5 (deacetylated PS-5) by l-amino acid acylase from porcine kidney and D-amino acid acylase from Streptomyces olivaceus but not by l-amino acid acylase from Aspergillus sp. Using PS-5, N-chloroacetyl-l-phenylalanine and N-chloroacetyl-D-valine as substrates, acylase producers were

The aminoacylase that catalyzes the hydrolysis of N-acetyl-L-cysteine (NAC) was identified as acylase I after purification by column chromatography and electrophoretic analysis. Rat kidney cytosol was fractionated by ammonium sulfate precipitation, and the proteins were separated by ion-exchange column chromatography
