A RACEMIZING ENZYME SYSTEM OF LACTOBACILLUS PLANTARUM

Abstract

As a result of quantitative studies, the racemization of lactate in Loctobacillus plantarum was found to be a cooperative reaction catalyzed by NAD-linked D- and L-lactate dehydrogenases. Any positive evidence of the existence of lactate racemase as a single enzyme in this organism could not be obtained. The former "Racemiase" is concluded to be a mixture of two enzymes.
