ID 1.8.2.7 DE Thiocyanate desulfurase. AN Thiocyanate dehydrogenase. CA Thiocyanate + 2 ferricytochrome c + H(2)O = cyanate + sulfur + CA 2 ferrocytochrome c + 2 H(+). CC -!- The enzyme, characterized from the haloalkaliphilic sulfur-oxidizing CC bacterium Thioalkalivibrio paradoxus, contains three copper ions in CC its active site. CC -!- It catalyzes the direct conversion of thiocyanate into cyanate and CC elemental sulfur without involvement of molecular oxygen. //
