Webchrome b 5 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. WebOct 18, 2024 · Dietary non-heme ferric iron is reduced by the ferric reductase enzyme, duodenal cytochrome b (Dcytb), before absorption by the divalent metal transporter 1 (DMT1). A single nucleotide polymorphism (SNP rs10455 mutant) that is located in the last exon of the Dcytb gene was reported in C282Y haemochromatosis HFE subjects.
