EC Number 1.97.1.4
CAS Registry Number 206367-15-9
Comments An iron-sulfur protein. A single glycine residue in EC 2.3.1.54, formate C-acetyltransferase, is oxidized to the corresponding radical by transfer of H from its CH2 to S-adenosyl-L-methionine (AdoMet) with concomitant cleavage of the latter. The reaction requires Fe2+. The first stage is reduction of the AdoMet to give methionine and the 5′-deoxyadenosin-5′-yl radical, which then abstracts a hydrogen radical from the glycine residue.
Cofactor iron-sulfur
History
Reactions S-adenosyl-L-methionine + dihydroflavodoxin + [formate C-acetyltransferase]-glycine = 5′-deoxyadenosine + L-methionine + flavodoxin semiquinone + [formate C-acetyltransferase]-glycin-2-yl radical.
