Catalysis of an oxidation-reduction (redox) reaction in which NADH or NADPH acts as a hydrogen or electron donor and reduces a heme protein. Catalysis of the reaction: NADH + H+ + 2 ferricytochrome b(5) = NAD+ + 2 ferrocytochrome b(5). Catalysis of the reaction: NADPH + H+ + n oxidized hemoprotein = NADP+ + n reduced hemoprotein. Catalysis of an oxidation-reduction (redox) reaction in which NADH or NADPH acts as a hydrogen or electron donor and reduces a hydrogen or electron acceptor. Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced. Catalysis of the reaction: NADPH + H+ + 2 ferricytochrome c2 = NADP+ + 2 ferrocytochrome c2. Catalysis of the reaction: NADPH + H+ + 2 ferrileghemoglobin = NADP+ + 2 ferroleghemoglobin.
