Glucose 6-phosphate dehydrogenase from Leuconostoc mesenteroides has a subunit molecular weight of 55,000, determined by SDS gel electrophoresis. The amino acid composition of the enzyme is reported. An unusual feature which has not been reported for any other dehydrogenase, is the complete absence of cystine or cysteine. This establishes the fact that cysteine is not an obligatory participant in the mechanism of action of NAD(P)-linked dehydrogenases. © 1974 Academic Press, Inc.
