EC 1.6 - Acting on NADH or NADPH


In general, enzymes using NADH or NADPH to reduce a substrate are classified according to the reverse reaction, in which NAD+ or NADP+ is formally regarded as acceptor. This subclass contains only those enzymes in which some other redox carrier is the acceptor. This can be NAD+ or NADP+ (EC 1.6.1), a heme protein (EC 1.6.2), oxygen (EC 1.6.3), a quinone or similar compound (EC 1.6.5), a nitrogenous group (EC 1.6.6), or some other acceptor (EC 1.6.99).

EC 1.6.3

EC 1.6.4

EC 1.6.5
With a quinone or similar compound as acceptor
EC 1.6.6

EC 1.6.99
With other acceptors
