Determination of Carboxypeptidase Activity in Clinical Pathogens by Gas Chromatography-Mass Spectrometry.

A novel method for the determination of benzoic acid has been employed to identify carboxypeptidase activities in clinically relevant pathogens. Benzoic acid was determined after chemical derivatization by gas chromatography-mass spectrometry (GC-MS). N-Benzoyl amino acid substrates were evaluated for the detection of carboxypeptidase activities in a number… CONTINUE READING
