pfam13501: SoxY (This model is not part of the current CDD release)
Sulfur oxidation protein SoxY
This domain is found in the sulfur oxidation protein SoxY. It is closely related to the Desulfoferrodoxin family pfam01880. Dissimilatory oxidation of thiosulfate is carried out by the ubiquitous sulfur-oxidizing (Sox) multi-enzyme system. In this system, SoxY plays a key role, functioning as the sulfur substrate-binding protein that offers its sulfur substrate, which is covalently bound to a conserved C-terminal cysteine, to another oxidizing Sox enzyme. The structure of this domain shows an Ig-like fold.
