Description: | 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. | ||||
Curator notes: | This reaction is missing a structure for the semi-quinone product, therefore will not chemically balance at this time. |
