For 10 points, name this enzyme found within red blood cells, which catalyzes the inter-conversion between carbon dioxide and carbonic acid.
This enzyme's alpha form can catalyze the hydration of aldehydes to gem-diols. In parietal cells it aids in introducing H+ to the lumen, while it plays the opposite role in pancreatic duct cells. Its catalytic site contains three histadine (*) residues which coordinate a central zinc bound water molecule for nucleophilic attack on a carbon dioxide molecule in the substrate binding domain.
