Reaction: 2 reduced rubredoxin + NAD+ + H+ = 2 oxidized rubredoxin + NADH
Glossary entries:
rubredoxin = iron-containing protein found in sulfur-metabolizing bacteria and archaea, participating in electron transfer
Other name(s): rubredoxin reductase; rubredoxin-nicotinamide adenine dinucleotide reductase; dihydronicotinamide adenine dinucleotide-rubredoxin reductase; reduced nicotinamide adenine dinucleotide-rubredoxin reductase; NADH-rubredoxin reductase; rubredoxin-NAD reductase; NADH: rubredoxin oxidoreductase; DPNH-rubredoxin reductase; NADH-rubredoxin oxidoreductase
Systematic name: rubredoxin:NAD+ oxidoreductase
Comments: Requires FAD. The enzyme from Clostridium acetobutylicum reduces rubredoxin, ferricyanide and dichlorophenolindophenol, but not ferredoxin or flavodoxin. The reaction does not occur when NADPH is substituted for NADH. Contains iron at the redox centre. Formerly EC 1.6.7.2.
