ENZYME entry: EC 4.1.99.19

Accepted Name
2-iminoacetate synthase.
Reaction catalysed
L-tyrosine + S-adenosyl-L-methionine + reduced acceptor <=> 2-iminoacetate + 4-methylphenol + 5'-deoxyadenosine + L-methionine + acceptor + 2 H(+)
Cofactor(s)
Iron-sulfur.
Comment(s)
  • 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 methionine and a 5-deoxyadenosin-5-yl radical that is crucial for the conversion of the substrate.
  • Part of the pathway for thiamine biosynthesis.
  • Formerly EC 1.3.99.n2.
