Abstract

Desulfoferrodoxins contains two types of iron: an Fe-S4 site very similar to that found in desulfoferrodoxin from Desulfovibrio gigas, and an octahedral coordinated high-spin ferrous site most probably with nitrogen/oxygen-containing ligands. Due to this rather unusual combination of active centres, this novel protein is named desulfoferrodoxin [PubMed2174880].

This domain comprises essentially the full length of neelaredoxin (, [PubMed8001576]), a monomeric, blue, non-haeme iron protein of D. gigas said to bind two iron atoms per monomer with identical spectral properties. Neelaredoxin was shown recently to have significant superoxide dismutase activity [PubMed9914498]. This domain is also found (in a form in which the distance between the motifs H[HWYF]IXW and CN[IL]HGXW is somewhat shorter) as the C-terminal domain of desulfoferrodoxin, which is said to bind a single ferrous iron atom. The N-terminal domain of desulfoferrodoxin is described by .

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 Superoxide reductase-like 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 Superoxide reductase-like superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
