KEGG   ENZYME: 2.1.1.342
Entry
EC 2.1.1.342                Enzyme                                 
Name
anaerobilin synthase;
chuW (gene name)
Class
Transferases;
Transferring one-carbon groups;
Methyltransferases
Sysname
S-adenosyl-L-methionine:protoheme C-methyltransferase (anaerobilin-producing)
Reaction(IUBMB)
2 S-adenosyl-L-methionine + protoheme + 2 reduced flavodoxin = S-adenosyl-L-homocysteine + L-methionine + 5'-deoxyadenosine + anaerobilin + Fe2+ + 2 oxidized flavodoxin [RN:R11700]
Reaction(KEGG)
R11700
Substrate
S-adenosyl-L-methionine [CPD:C00019];
protoheme [CPD:C00032];
reduced flavodoxin [CPD:C02745]
Product
S-adenosyl-L-homocysteine [CPD:C00021];
L-methionine [CPD:C00073];
5'-deoxyadenosine [CPD:C05198];
anaerobilin [CPD:C21603];
Fe2+ [CPD:C14818];
oxidized flavodoxin [CPD:C02869]
Comment
The enzyme, studied from the bacterium Escherichia coli O157:H7, is a radical SAM (AdoMet) enzyme that is involved in heme degradation and iron utilization under anaerobic conditions. The enzyme uses two SAM molecules for the reaction. The first molecule is used to generate a 5'-deoxyadenosyl radical, which abstracts a hydrogen atom from the methyl group of the second SAM molecule. The newly formed methylene radical attacks the substrate, causing a rearrangement of the porphyrin ring that results in the liberation of iron.
