N-phenylglycolhydroxamate production by the action of transketolase on nitrosobenzene

Abstract

The incubation of nitrosobenzene with yeast transketolase and D-xylulose 5-phosphate resulted in the production of N-phenylglycolhydroxamic acid. The addition of D-ribose 5-phosphate decreased the amount of hydroxamic acid that was produced. This conversion of nitrosobenzene into the glycollic acid-derived hydroxamic acid was shown to be an enzymic process, and a chemical mechanism for the conversion was proposed.
