Chains	Enzyme Name	Description	Catalytic Residues
A	carbonate dehydratase (beta class) M-CSA #517	Beta-carbonic anhydrases are found in a variety of higher plants, simple eukaryotes, eubacteria and archaea. they catalyse the interconversion of carbon dioxide and bicarbonate. These are zinc-containing metalloenzymes.
