Domain relationships


Rubredoxin is a low molecular weight iron-containing bacterial protein involved in electron transfer [PMID: 2244884, PMID: 1992166], sometimes replacing ferredoxin as an electron carrier [PMID: 7726577]. Rubredoxins possess a 45- to 55-residue domain containing one iron atom tetrahedrally coordinated to four cysteinyl residues. Structural analysis of the domains have shown them to be folded into a short three-stranded antiparallel beta-sheet and a number of loops [PMID: 3441010, PMID: 1303768, PMID: 7830611, PMID: 8646540].
