Bidirectionality of the CODH/ACS complex (IMAGE) Max Planck Institute for Marine Microbiology Caption This graphic shows the bidirectionality of the CODH/ACS complex from C. autoethanogenum (CODH in orange and ACS in purple). Under chemolithoautotrophic conditions, the enzyme can transform the carbon dioxide (CO2) in carbon monoxide (CO), sequestered in a gas channel (top). The CO will be turned into acetyl-CoA, the building block of the cell used to obtain cellular energy and build the cell material. During the gas conversion process, the CO released by industrial activity can be very efficiently used by the CODH/ACS (bottom). It is captured by the numerous gas channel and will generate Acetyl-CoA and chemical energy at the same time, allowing the cell to make a life out of CO. Credit O. Lemaire and T. Wagner.
