Sysname
L-lysine carboxy-aminomethylmutase
Reaction(IUBMB)
L-lysine = (3R)-3-methyl-D-ornithine [RN:R10010]
Reaction(KEGG)
R10010
Substrate
L-lysine [CPD:C00047]
Product
(3R)-3-methyl-D-ornithine [CPD:C20277]
Comment
The enzyme is a member of the superfamily of S-adenosyl-L-methionine-dependent radical (radical AdoMet) enzymes. Binds a [4Fe-4S] cluster that is coordinated by 3 cysteines and an exchangeable S-adenosyl-L-methionine molecule. The reaction is part of the biosynthesis pathway of pyrrolysine, a naturally occurring amino acid found in some archaeal methyltransferases.
