Description

Carboxysome Shell Carbonic Anhydrase is a bacterial carbonic anhydrase localised in the carboxysome, where it converts bicarbonate ions to carbon dioxide for use in carbon fixation. It contains three domains, these being: (1) an N-terminal domain composed primarily of four alpha-helices; (2) a catalytic domain containing a tightly bound zinc ion and (3) a C-terminal domain with weak structural similarity to the catalytic domain
