CO-methylating acetyl-CoA synthase

In enzymology, a CO-methylating acetyl-CoA synthase is an enzyme that catalyzes the chemical reaction


 * acetyl-CoA + corrinoid protein $$\rightleftharpoons$$ CO + methylcorrinoid protein + CoA

Thus, the two substrates of this enzyme are acetyl-CoA and corrinoid protein, whereas its 3 products are CO, methylcorrinoid protein, and CoA.

This enzyme belongs to the family of transferases, specifically those acyltransferases transferring groups other than aminoacyl groups. The systematic name of this enzyme class is acetyl-CoA:corrinoid protein O-acetyltransferase.
