Methylornithine synthase.
based on mapping to UniProt Q46E78
L-lysine = (3R)-3-methyl-D-ornithine.
-!- 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.
