6.3.2.59

Accepted name:

3-methyl-D-ornithine—L-lysine ligase

Reaction:

ATP + (3R)-3-methyl-D-ornithine + L-lysine = ADP + phosphate + N⁶-[(3R)-3-methyl-D-ornithinyl]-L-lysine

Glossary:

L-pyrrolysine = N⁶-{[(2R,3R)-3-methyl-3,4-dihydro-2H-pyrrol-2-yl]carbonyl}-L-lysine

Other name(s):

N⁶-[(2R,3R)-3-methylornithyl]-L-lysine synthase; 3-methylornithine—L-lysine ligase; pylC (gene name)

Systematic name:

(3R)-3-methyl-D-ornithine:L-lysine γ-ligase (ADP-forming)

Comments:

The enzyme participates in the biosynthesis of L-pyrrolysine, a naturally occurring, genetically coded amino acid found in some methanogenic archaea and a few bacterial species. L-pyrrolysine is present in several methyltransferases that are involved in methyl transfer from methylated amine compounds to coenzyme M.
