CO + a quinone + H2O = CO2 + a quinol | reaction mechanism that initially involves nucleophilic attack of a Mo=O oxo on the carbon center of Cu(I)-CO, resulting in a 5-membered cyclic m2-e(2) CO2-bridged Mo(VI)-Cu(I)-Cys complex I that can bind HO-/H2O to yield 1-OH. This is followed by a second nucleophilic attack on the activated mu2-nu2 CO2 carbon centre of 1-OH to yield a Mo(IV)-bicarbonate product complex, 1-P. This second nucleophilic attack is suggested based on electronic structure description of cyclic m2-e(2) CO2-bridged Mo(VI)-Cu(I)-Cys complex I, which possesses a bent and activated CO2 bound to the Mo and Cu ions. Proposed catalytic cycle for CODH that avoids formation of a stable C-S bonded cyclic m2-e(2) CO2-bridged Mo(VI)-Cu(I)-Cys complex II | Hydrogenophaga pseudoflava | |
