PFAM accession number:PF00174
Interpro abstract (IPR000572):

A number of different eukaryotic oxidoreductases that require and bind a molybdopterin cofactor have been shown [(PUBMED:2015248)] to share a few regions of sequence similarity. These enzymes include xanthine dehydrogenase (EC, aldehyde oxidase (EC, nitrate reductase (EC, and sulphite oxidase (EC The multidomain redox enzyme NAD(P)H:nitrate reductase (NR) catalyses the reduction of nitrate to nitrite in a single polypeptide electron transport chain with electron flow from NAD(P)H-FAD-cytochrome b5-molybdopterin-NO(3). Three forms of NR are known, an NADH-specific enzyme found in higher plants and algae (EC; an NAD(P)H-bispecific enzyme found in higher plants, algae and fungi (EC; and an NADPH-specific enzyme found only in fungi (EC [(PUBMED:2204158)]. The mitochondrial enzyme sulphite oxidase (sulphite:ferricytochrome c oxidoreductase; EC catalyses oxidation of sulphite to sulphate, using cytochrome c as the physiological electron acceptor. Sulphite oxidase consists of two structure/function domains, an N-terminal haem domain, similar to cytochrome b5; and a C-terminal molybdopterin domain [(PUBMED:9428520)].
