NAD-specific 6-phosphogluconate dehydrogenase in lactic acid bacteria.
6-Phosphogluconate dehydrogenase was screened in for cell-free extracts from seventeen strains of lactic acid bacteria. Three types of the enzyme could be classified according to the coenzyme specificity: NAD-specific, NADP-specific, and non-specific types. The two strains that had a heterofermentative pathways had an NAD-specific 6-phosphogluconate dehydrogenase. This type had higher enzyme activity per proteins in the cell-free extracts, and more specificity to NAD compared to the other types of the enzyme in the lactic acid bacteria studied.
