BRITE hierarchy
Sysname
carbon-disulfide hydrogen-sulfide-lyase (decarboxylating)
Reaction(IUBMB)
carbon disulfide + 2 H2O = CO2 + 2 hydrogen sulfide (overall reaction) [RN:R10538];
(1a) carbon disulfide + H2O = carbonyl sulfide + hydrogen sulfide [RN:R10534];
(1b) carbonyl sulfide + H2O = CO2 + hydrogen sulfide [RN:R10535]
Reaction(KEGG)
Substrate
carbon disulfide [CPD:C19033];
H2O [CPD:C00001];
carbonyl sulfide [CPD:C07331]
Product
CO2 [CPD:C00011];
hydrogen sulfide [CPD:C00283];
carbonyl sulfide [CPD:C07331]
Comment
The enzyme contains Zn2+. The hyperthermophilic archaeon Acidianus sp. A1-3 obtains energy by the conversion of carbon disulfide to hydrogen sulfide, with carbonyl sulfide as an intermediate.
