Chains	Enzyme Name	Description	Catalytic Residues
A	thiosulfate sulfurtransferase (eukaryotic) M-CSA #153	Thiosulfate sulfurtransferase (rhodanese) is an ubiquitous enzyme that in vitro catalyses the transfer of a sulfur atom from suitable donors to nucleophilic acceptors by way of a double displacement mechanism. During the catalytic process the enzyme cycles between a sulfur-free and a persulfide-containing form, via formation of a persulfide linkage to a catalytic Cys residue.
