Chains	Enzyme Name	Description	Catalytic Residues
A	carbonate dehydratase (gamma class) M-CSA #516	Gamma-class carbonic anhydrase (Cam) from Methanosarcina thermophila catalyses the reversible hydration of carbon dioxide to bicarbonate. There are three distinct classes of carbonic anhydrases (alpha, beta and gamma). In M. thermophila, Cam activity increases when the substrate for growth is acetate, suggesting the involvement of this enzyme in acetate catabolism.
