EC 2.5.1.120     
Accepted name: aminodeoxyfutalosine synthase
Reaction: S-adenosyl-L-methionine + 3-[(1-carboxyvinyl)oxy]benzoate + H2O = 6-amino-6-deoxyfutalosine + L-methionine + HCO3-

Glossary: 6-amino-6-deoxyfutalosine = 3-{3-[(2R,3S,4R,5R)-5-(6-amino-9H-purin-9-yl)-3,4-dihydroxytetrahydrofuran-2-yl]propanoyl}benzoate
Other name(s): MqnE; AFL synthase; aminofutalosine synthase; S-adenosyl-L-methionine:3-[(1-carboxyvinyl)-oxy]benzoate adenosyltransferase (bicarbonate-hydrolysing, 6-amino-6-deoxyfutalosine-forming)
Systematic name: S-adenosyl-L-methionine:3-[(1-carboxyvinyl)-oxy]benzoate adenosyltransferase (HCO3--hydrolysing, 6-amino-6-deoxyfutalosine-forming)
Comments: This enzyme is a member of the ‘AdoMet radical’ (radical SAM) family. S-Adenosyl-L-methionine acts as both a radical generator and as the source of the transferred adenosyl group. The enzyme, found in several bacterial species, is part of the futalosine pathway for menaquinone biosynthesis.
