A newly discovered energy-linked carbonic anhydrase, DabBA2, is a two-protein complex responsible for inorganic carbon accumulation in the sulfur bacterium Halothiobacillus neapolitanus. DABs are present in a wide range of proteobacterial clades, suggesting that they function in diverse metabolic pathways.
