>cd02034 CooC The accessory protein CooC, which contains a nucleotide-binding domain (P-loop) near the N-terminus, participates in the maturation of the nickel center of carbon monoxide dehydrogenase (CODH). CODH from Rhodospirillum rubrum catalyzes the reversible oxidation of CO to CO2. CODH contains a nickel-iron-sulfur cluster (C-center) and an iron-sulfur cluster (B-center). CO oxidation occurs at the C-center. Three accessory proteins encoded by cooCTJ genes are involved in nickel incorporation into a nickel site. CooC functions as a nickel insertase that mobilizes nickel to apoCODH using energy released from ATP hydrolysis. CooC is a homodimer and has NTPase activities. Mutation at the P-loop abolishs its function.
