2.3.1.169 | acetyl-CoA + a [Co(I) corrinoid Fe-S protein] = CO + CoA + a [methyl-Co(III) corrinoid Fe-S protein] | pathway | Moorella thermoacetica | |
2.3.1.169 | acetyl-CoA + a [Co(I) corrinoid Fe-S protein] = CO + CoA + a [methyl-Co(III) corrinoid Fe-S protein] | Enzyme accepts the methyl group from the methylated corrinoid/iron-sulfur protein, binds a carbonyl group from CO, CO2, or the carboxyl of pyruvate, and binds coenzyme A. Then the enzyme catalyses the synthesis of acetyl-CoA from these enzyme bound groups. Additionally the enzyme catalyses two exchange reactions between the methylated corrinoid/iron-sulfur protein and methylated enzyme and between methylated enzyme and the methyl moiety of acetyl-CoA. | Moorella thermoacetica |
