show Brenda entry

EC number

3.13.1.7

Accepted name

carbonyl sulfide hydrolase

Reaction

carbonyl sulfide + H₂O = hydrogen sulfide + CO₂

Other name(s)

COSase, COS hydrolase, cos (gene name)

Systematic name

carbonyl sulfide hydrogen-sulfide-lyase (decarboxylating)

Comment

The enzyme, characterized from the bacterium Thiobacillus thioparus, catalyses a step in the degradation pathway of thiocyanate. This activity is also catalysed by the archaeal EC 3.13.1.5, carbon disulfide lyase.
