1.1.1.82 NAD+ NADP+ is the preferred cofactor compared to NAD+ with substrate (S)-malate, while NAD+ is preferred with substrate tartrate. Ala at position 53 is responsible for coenzyme specificity, and the next residue, Arg, is important for NADP+ binding, structural analysis and comparison 696461 1.1.1.82 NADP+ - 739249, 740926, 741200, 762295, 762354 1.1.1.82 NADP+ NADP+ binds to Ser9, Arg34, His36, Ser37, Ile121, Asn123, and Glu219 740926 1.1.1.82 NADP+ NADP+ is the preferred cofactor compared to NAD+ with substrate (S)-malate, while NAD+ is preferred with substrate tartrate.
