ID 2.1.1.344 DE ornithine lipid N-methyltransferase. CA an N(2)-[(3R)-3-(2-saturated-acyloxy)acyl]-L-ornithine lipid + CA 3 S-adenosyl-L-methionine = an N,N,N-trimethylornithine lipid + 3 H(+) + CA 3 S-adenosyl-L-homocysteine. CC -!- The enzyme, characterized from the bacterium Singulisphaera CC acidiphila, catalyzes three successive methylations of the terminal CC delta-nitrogen in ornithine lipids.
