NAD(P)H:rubredoxin oxidoreductase

UniProtKB accession:  Q8U1K9

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalyzes the NADH-dependent reduction of rubredoxin (Rd), a small iron-containing redox protein (PubMed:10464233, PubMed:11398485, PubMed:15746356). Can also reduce other electron carriers, including 2,6-dichlorophenol indophenol, benzyl viologen and menadione, but rubredoxin is the most efficient electron acceptor (PubMed:10464233, PubMed:11398485, PubMed:15746356). Does not reduce ferredoxin (PubMed:10464233). Shows comparable activity with NADPH and NADH as electron donors, but NADPH is probably the preferred physiological electron donor (PubMed:10464233, PubMed:11398485). Is probably part of an oxygen detoxification system that protects P.furiosus during exposure to oxygen (PubMed:15746356).
