EC 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)

Comments: 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.
