In the next step, a proton-assisted second electron transfer takes place with a conserved active-site histidine serving as the second proton donor. The electron for the second reduction step is taken from the pyranopterin cofactors rather than from the tungsten ion. The resulting cationic radical, which is distributed over both pyranopterins, is stabilized by conserved anionic amino acid residues, reaction mechanism, detailed overview -, 763184 1.3.7.8 cyclohexa-1,5-diene-1-carbonyl-CoA + oxidized ferredoxin + 2 ADP + 2 phosphate = benzoyl-CoA + reduced ferredoxin + 2 ATP + 2 H2O Birch-like mechanism 654733 1.3.7.8 cyclohexa-1,5-diene-1-carbonyl-CoA + oxidized ferredoxin + 2 ADP + 2 phosphate = benzoyl-CoA + reduced ferredoxin + 2 ATP + 2 H2O Birch-like reduction with base-catalyzed rearrangement to 1,5-diene 285200 1.3.7.8 cyclohexa-1,5-diene-1-carbonyl-CoA + oxidized ferredoxin + 2 ADP + 2 phosphate = benzoyl-CoA + reduced ferredoxin + 2 ATP + 2 H2O class II BCRs drive BzCoA reduction by flavin-based electron bifurcation (FBEB) -, 762977 1.3.7.8 cyclohexa-1,5-diene-1-carbonyl-CoA + oxidized ferredoxin + 2 ADP + 2 phosphate = benzoyl-CoA + reduced ferredoxin + 2 ATP + 2 H2O reaction mechanism, quantum mechanical/molecular mechanical (QM/MM) calculations 763132
