Dissolved Inorganic Carbon-Accumulating Complexes from Autotrophic Bacteria from Extreme Environments.

ABSTRACT: In nature, concentrations of dissolved inorganic carbon (DIC; CO₂ + HCO₃^- + CO₃^2-) can be low, and autotrophic organisms adapt with a variety of mechanisms to elevate intracellular DIC concentrations to enhance CO₂ fixation. Such mechanisms have been well studied in Cyanobacteria, but much remains to be learned about their activity in other phyla. Novel multisubunit membrane-spanning complexes capable of elevating intracellular DIC were recently described in three species of bacteria. Homologs of these complexes are distributed among 17 phyla in Bacteria and Archaea and are predicted to consist of one, two, or three subunits. To determine whether DIC accumulation is a shared feature of these diverse comp
