| Comments |
Binds a [4Fe-4S] cluster that is coordinated by 3 cysteines and an exchangeable?S-adenosyl-L-methionine molecule. The first stage of catalysis is reduction of the?S-adenosyl-L-methionine to produce?L-methionine and a 5′-deoxyadenosin-5′-yl radical that is crucial for the conversion of the substrate. Part of the pathway for thiamine biosynthesis. |

| Reactions |
5-amino-1-(5-phospho-D-ribosyl)imidazole + S-adenosyl-L-methionine = 4-amino-2-methyl-5-(phosphomethyl)pyrimidine + 5′-deoxyadenosine + L-methionine + formate + Co. |
