1 | The reduction of exogenous cytochrome b5 by microsomes was low at 1.2 microM cytochrome b5 (3.9 or 2.7 nmol/min/mg protein, respectively, with NADH or NADPH). | NAD | cytochrome b5 type A | Homo sapiens |
2 | The reduction of exogenous cytochrome b5 by microsomes was low at 1.2 microM cytochrome b5 (3.9 or 2.7 nmol/min/mg protein, respectively, with NADH or NADPH). | NAD | cytochrome b5 type A | Homo sapiens |
3 | MgCl2 also stimulated cytochrome b5 reduction with a EC50 value of 1.0 mM in the NADH system or 0.6 mM in the NADPH system. | NAD | cytochrome b5 type A | Homo sapiens |
4 | The Km value for cytochrome b5 was decreased and the Vmax was increased by calcium with either the NADH- or the NADPH-dependent system. | NAD | cytochrome b5 type A | Homo sapiens |
5 | In the presence of Triton X-100, divalent cations were inhibitory in NADH-dependent cytochrome b5 reduction, and in contrast, stimulative in NADPH-dependent reaction. | NAD | cytochrome b5 type A | Homo sapiens |
6 | These findings suggest that the activation of cytochrome b5 reduction by divalent cations in the NADH system is mainly due to an increasing accessibility of the substrate, and in the NADPH system, in addition to this, a direct effect of divalent cations on NADPH-cytochrome P450 reductase is also involved. | NAD | cytochrome b5 type A | Homo sapiens |
