its catalytic efficiency is 33times higher with NAD+ than with NADP+
NAD(P)H
MtDH has a higher Vmax with NADPH than with NADH, whereas its catalytic efficiency is 2.2times higher with NADH than with NADPH. Cofactor specificity is due to the high density of negatively charged residues (Glu193, Asp195, and Glu196) downstream of the NAD(P) interaction site, the glycine motif
NADP+
