IUBMB Enzyme Nomenclature

EC 1.8.2.7

Accepted name: thiocyanate desulfurase

Reaction: thiocyanate + 2 ferricytochrome c + H2O = cyanate + sulfur + 2 ferrocytochrome c + 2 H+

Other name(s): TcDH; thiocyanate dehydrogenase

Systematic name: thiocyanate:cytochrome c oxidoreductase (cyanate and sulfur-forming)

Comments: The enzyme, characterized from the haloalkaliphilic sulfur-oxidizing bacterium Thioalkalivibrio paradoxus, contains three copper ions in its active site. It catalyses the direct conversion of thiocyanate into cyanate and elemental sulfur without involvement of molecular oxygen.
