Abstract

A number of different eukaryotic oxidoreductases that require and bind a molybdopterin cofactor have been shown [PubMed2015248] to share a few regions of sequence similarity. These enzymes include xanthine dehydrogenase , aldehyde oxidase , nitrate reductase , and sulphite oxidase . The multidomain redox enzyme NAD(P)H:nitrate reductase (NR) catalyzes 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 ; an NAD(P)H-bispecific enzyme found in higher plants, algae and fungi ; and an NADPH-specific enzyme found only in fungi [PubMed2204158]. The mitochondrial enzyme sulphite oxidase (sulphite:ferricytochrome c oxidoreductase; EC 1.8.2.1) catalyses oxidation of sulphite to sulphate, using cytochrome c as the physiological electron acceptor. Sulphite oxidase consists of 2 structure/function domains, an N-terminal heme domain, similar to cytochrome b5; and a C-terminal molybdopterin domain [PubMed9428520].

Browse genome assignments for this superfamily. The SUPERFAMILY hidden Markov model library has been used to carry out SCOP domain assignments to all genomes at the superfamily level.


Alignments of sequences to 3 models in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.


Browse and view proteins in genomes which have different domain combinations including a Oxidoreductase molybdopterin-binding domain domain.


Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.


Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.

There are 3 hidden Markov models representing the Oxidoreductase molybdopterin-binding domain superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
