(3S)-3-hydroxy-N6,N6,N6-trimethyl-L-lysine + succinate + CO2
the enzymatic hydroxylation occurs at the C-3 site of (2S)-Nepsilon-trimethyllysine substrate. Comparative NMR spectroscopic studies (with two enantiopure synthetic standards that possess 3R and 3S stereochemistry) on the enzymatically produced (2S)-3-hydroxy-Nepsilon-trimethyllysine reveal that TMLH exclusively catalyzes the formation of (3S)-3-hydroxy-Nepsilon-trimethyl-L-lysine, not forming any (3R)-3-hydroxy-Nepsilon-trimethyl-L-lysine diastereoisomer
