A genome-wide transposon screen in Halothiobacillus neapolitanus identifies genes involved in CO2 concentrating mechanisms, of which dabA and dabB encode a heterodimeric complex that works as an energy-coupled inorganic carbon pump. Dab homologues exist in multiple archaea and bacteria, including pathogens such as Bacillus anthracis and Vibrio cholerae.
