Function
function
Involved in the biosynthesis of the coenzyme M (2-mercaptoethanesulfonic acid). Catalyzes the decarboxylation of sulfopyruvate to sulfoacetaldehyde.
Catalytic activity
- 3-sulfopyruvate + H+ = sulfoacetaldehyde + CO2
Cofactor
Note: Binds 1 thiamine pyrophosphate per subunit.
Pathway
Cofactor biosynthesis; coenzyme M biosynthesis; sulfoacetaldehyde from phosphoenolpyruvate and sulfite: step 4/4.
