Identification of an NADH-linked disulfide reductase from Bacillus megaterium specific for disulfides containing...

Bacillus megaterium contains an NADH-linked disulfide reductase that is specific for disulfides containing pantethine 4',4''-diphosphate moieties. This reductase is at its highest level in cells late in sporulation and in dormant spores, and could be involved in the formation and cleavage of coenzyme A-protein disulfides which take place late in sporulation and early in spore germination, respectively.
