ENTRY       EC 1.6.1.1
NAME        NAD(P)+ transhydrogenase (B-specific)
            Pyridine nucleotide transhydrogenase
            Transhydrogenase
CLASS       Oxidoreductases
            Acting on NADH or NADPH
            With NAD+ or NADP+ as acceptor
SYSNAME     NADPH:NAD+ oxidoreductase (B-specific)
REACTION    NADPH + NAD+ = NADP+ + NADH
SUBSTRATE   NADPH
            NAD+
PRODUCT     NADP+
            NADH
COFACTOR    FAD
COMMENT     The enzyme from Azotobacter vinelandii is a flavoprotein (FAD).
            It is B-specific with respect to both NAD+ and NADP+.
            Also acts on deamino coenzymes (cf. EC 1.6.1.2).
