Abstract

Sulphate-reducing bacteria possess many redox proteins including some flavoproteins. Flavodoxins are a group of proteins with a tightly bound flavin mononucleotide (FMN) that mediate electron transfer at low redox potential. A novel FMN-binding protein from Desulphovibrio vulgaris has been cloned and crystallised and shown to be composed of 122 amino acids making it the smallest of the known proteins which bind FMN [PubMed10713530]. The exact function of this protein is unknown but it may take part in the electron-transfer pathway. The structure has been shown to contain a FMN-binding split barrel, which is related to the ferredoxin reductase-like FAD-binding domain.

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 49 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 FMN-binding split barrel 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 49 hidden Markov models representing the FMN-binding split barrel superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
