ID 5.4.99.58 DE methylornithine synthase. CA L-lysine = (3R)-3-methyl-D-ornithine. CC -!- The enzyme is a member of the superfamily of S-adenosyl-L-methionine- CC dependent radical (radical AdoMet) enzymes. CC -!- Binds a [4Fe-4S] cluster that is coordinated by 3 cysteines and an CC exchangeable S-adenosyl-L-methionine molecule. CC -!- The reaction is part of the biosynthesis pathway of pyrrolysine, CC a naturally occurring amino acid found in some archaeal CC methyltransferases.
