Abstract

A gas-liquid chromatographic procedure is described for the determination of nitrilasic and amidasic activities. This method allows to monitor the kinetics of the hydrolysis of volatile nitriles and amides and because of its sensitivity, to determine the Michaelis constants Km of the acetonitrilase and the acetamidase of Brevibacterium R 312. For these enzymes, a correlation is shown between the kinetics monitored by proton nuclear magnetic resonance spectroscopy and gas-liquid chromatography.
