ID 6.3.2.59 DE 3-methyl-D-ornithine--L-lysine ligase. AN 3-methylornithine--L-lysine ligase. AN N(6)-[(2R,3R)-3-methylornithyl]-L-lysine synthase. CA (3R)-3-methyl-D-ornithine + L-lysine + ATP = (3R)-3-methyl-D-ornithyl- CA N(6)-L-lysine + ADP + phosphate + H(+). CC -!- The enzyme participates in the biosynthesis of L-pyrrolysine, CC a naturally occurring, genetically coded amino acid found in some CC methanogenic archaea and a few bacterial species. CC -!- L-pyrrolysine is present in several methyltransferases that are CC involved in methyl transfer from methylated amine compounds to CC coenzyme M.
