Conversion of nitrosobenzene to N-phenylacetohydroxamic acid by yeast pyruvate decarboxylase. 1975

M D Corbett, and J E Cahoy, and B R Chipko

In the presence of yeast enzyme concentrate or purified yeast pyruvate decarboxylase, nitrosobenzene was converted in part to N-phenylacetohydroxamic acid. This transformation had to be catalyzed by the enzyme, since the incubation of nitrosobenzene with the cofactor of pyruvate decarboxylase did not produce the hydroxamic acid. Similar incubations conducted with phenylhydroxylamine did not yield any detectable amounts of N-phenylacetohydroxamic acid.

UI	MeSH Term	Description	Entries
D009578	Nitrobenzenes	BENZENE derivatives carrying nitro group substituents.
D011767	Pyruvate Decarboxylase	Catalyzes the decarboxylation of an alpha keto acid to an aldehyde and carbon dioxide. Thiamine pyrophosphate is an essential cofactor. In lower organisms, which ferment glucose to ethanol and carbon dioxide, the enzyme irreversibly decarboxylates pyruvate to acetaldehyde.
