RT   "Complete genomic sequence of Mycobacterium tuberculosis strain H37Ra,
RT   a non-pathogenic variant closely related to the well-characterized
RT   pathogenic strain H37Rv.";
RL   Submitted (MAR-2007) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Conversion of NADPH, generated by peripheral catabolic
CC       pathways, to NADH, which can enter the respiratory chain for
CC       energy generation (By similarity).
CC   -!- CATALYTIC ACTIVITY: NADPH + NAD(+) = NADP(+) + NADH.
CC   -!- COFACTOR: Binds 1 FAD per subunit (By similarity).
CC   -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity).
CC   -!- SIMILARITY: Belongs to the class-I pyridine nucleotide-disulfide
CC       oxidoreductase family.
