WebStudies in recent years have clarified this issue by delineating three pathways by which cytochrome b (5) augments P450 reactions: direct electron transfer of both required electrons from NADH-cytochrome b (5) reductase to P450, in a pathway separate and independent of NADPH-cytochrome P450 reductase; transfer of the second electron to ... Web5 reductase) showed virtually no activity for hydrox-ylamine reduction, compared with normal fibroblasts. These results indicate a novel direct role for NADH cytochrome b 5 reductase and cytochrome b 5 in xenobiotic metabolism and suggest that pharmacogenetic variability in either of these pro-teins may effect drug reduction capacity.
