Reaction: acetyl-CoA + a [Co(I) corrinoid Fe-S protein] = CO + CoA + a [methyl-Co(III) corrinoid Fe-S protein]
Systematic name: acetyl-CoA:corrinoid protein O-acetyltransferase
Comments: Contains nickel, copper and iron-sulfur clusters. Involved, together with EC 22.214.171.124, carbon-monoxide dehydrogenase (ferredoxin), in the synthesis of acetyl-CoA from CO2 and H2.
