1.7.2.4 | nitrogen + H2O + 2 ferricytochrome c = nitrous oxide + 2 ferrocytochrome c + 2 H+ |
spectroscopic definition of the CuZ* intermediate in turnover of nitrous oxide reductase and molecular insight into the catalytic mechanism. The nature of N2O binding and reduction, specifies a molecular mechanism in which N2O coordinates in a mu-1,3 fashion to the fully reduced state, with hydrogen bonding from Lys397, and two electrons are transferred from the fully reduced mu4S2-bridged tetranuclear copper cluster to N2O via a single Cu atom to accomplish N-O bond cleavage |
