Hog kidney Acylase I, an enzyme which hydrolyzes N-acetylL-amino acids, has been purified approximately 40-fold by Greenstein (1). During the course of the purification of hog kidney dialkylfluorophosphatase, it was consistently found that the protein fractions containing DFPasel activity also possessed very high Acylase I activity. Inasmuch as the DFPase and Acylase I activities were found to ...

The virulence of the opportunistic human pathogen Pseudomonas aeruginosa PAO1 is controlled by an N-acyl-homoserine lactone (AHL)-dependent quorum-sensing system. During functional analysis of putative acylase genes in the P. aeruginosa PAO1 genome, the PA2385 gene was found to encode an acylase that removes the fatty acid side chain from the homoserine lactone (HSL) nucleus of AHL-dependent qu...

Penicillin acylase catalyses the hydrolysis and synthesis of semisynthetic beta-lactam antibiotics via formation of a covalent acyl-enzyme intermediate. The kinetic and mechanistic aspects of these reactions were studied. Stopped-flow experiments with the penicillin and ampicillin analogues 2-nitro-5-phenylacetoxy-benzoic acid (NIPAOB) and d-2-nitro-5-[(phenylglycyl)amino]-benzoic acid (NIPGB) ...
