== Publication Abstract from PubMed ==
Carbonic anhydrase (CA) is a zinc enzyme that catalyzes the reversible conversion of carbon dioxide to bicarbonate and proton. Currently, CA inhibitors are widely used as antiglaucoma, anticancer, and anti-obesity drugs and for the treatment of neurological disorders. Recently, the potential use of CA inhibitors to fight infections caused by protozoa, fungi, and bacteria has emerged as a new research line. In this article, the X-ray crystal structure of beta-CA from Burkholderia pseudomallei was reported. The X-ray crystal structure of this new enzyme was solved at 2.7 A resolution, revealing a tetrameric type II beta-CA with a "closed" active site in which the zinc is tetrahedrally coordinated to Cys46, Asp48, His102, and Cys105. B. pseudomallei is known to encode at least two CAs, a beta-CA, and a gamma-CA. These proteins, playing a pivotal role in its life cycle and pathogenicity, offer a novel therapeutic opportunity to obtain antibiotics with a different mechanism of action. Furthermore, the new structure can provide a clear view of the beta-CA mechanism of action and the possibility to find selective inhibitors for this class of CAs.
