Carbonic anhydrases in bacterial pathogens.

Carbonic anhydrases (CAs) catalyze the reversable hydration of carbon dioxide to bicarbonate placing them into the core of the biochemical carbon cycle. Due to the fundamental importance of their function, they evolved independently into eight classes, three of which have been recently discovered. Most research on CAs has focused on their representatives in eukaryotic organisms, while prokaryotic CAs received significantly less attention. Nevertheless, prokaryotic CAs play a key role in the fundamental ability of the biosphere to acquire CO ₂ for photosynthesis and to decompose the organic matter back to CO ₂ . They also contribute to a broad spectrum of processes in pathogenic bacteria, enhancing their ability to survive in a host and, therefore, present a promising target for developing antimicrobials. This review focuses on the distribution of CAs among bacterial pathogens and their importance in bacterial virulence and host-pathogen interactions.
