[GOC:jl] EOG8X3KF8 GO:0050661 12/49 NADP binding molecular_function "Interacting selectively and non-covalently with nicotinamide-adenine dinucleotide phosphate, a coenzyme involved in many redox and biosynthetic reactions; binding may be to either the oxidized form, NADP+, or the reduced form, NADPH." [GOC:ai] EOG8X3KF8 GO:0008750 12/49 NAD(P)+ transhydrogenase (AB-specific) activity molecular_function "Catalysis of the reaction: NADPH + H+ + NAD+ = NADP+ + NADH + H+. The reaction is A-specific (i.e. the pro-R hydrogen is transferred from the 4-position of reduced nicotinamide cofactor) with respect to NAD+ and B-specific (i.e. the pro-S hydrogen is transferred) with respect to NADP+."
