ENZYME entry: EC 3.1.6.20
Accepted Name |
S-sulfosulfanyl-L-cysteine sulfohydrolase.
|
Reaction catalysed |
- [SoxY protein]-S-sulfosulfanyl-L-cysteine + H(2)O <=> [SoxY protein]-S-sulfanyl-L-cysteine + sulfate
- [SoxY protein]-S-(2-sulfodisulfanyl)-L-cysteine + H(2)O <=> [SoxY protein]-S-disulfanyl-L-cysteine + sulfate
|
Cofactor(s) |
Mn(2+).
|
Comment(s) |
- The enzyme is part of the Sox enzyme system, which participates in a
bacterial thiosulfate oxidation pathway that produces sulfate.
- It catalyzes two reactions in the pathway.
- In both cases the enzyme hydrolyzes a sulfonate moiety that is bound
(either directly or via a sulfane) to a cysteine residue of a SoxY
protein, releasing sulfate.
- The enzyme from Paracoccus pantotrophus contains a pyroglutamate
(cycloglutamate) at its N-terminus.
