Polysulfide-sulfurtransferase - Rhodanese Homology Domain. This domain is believed to serve as a polysulfide binding and transferase domain in anaerobic gram-negative bacteria, functioning in oxidative phosphorylation with polysulfide-sulfur as a terminal electron acceptor. The active site contains the same conserved cysteine that is the catalytic residue in other Rhodanese Homology Domain proteins.
