Abstract
A microsome-bound enzyme, which can be separated from rat kidney homogenates, splits the compound formed by the interaction of glutathione and fluoropyruvic acid with a concomitant increase in the UV light absorption. An analysis of the products and the pattern of the reaction suggest that the micro-somal enzyme is identical with gamma-glutamyltranspeptidase. By a spectrophotometric method some quantitative aspects of this enzyme activity have been studied.
