EC 1.14.11.58     
Accepted name: ornithine lipid ester-linked acyl 2-hydroxylase
Reaction: an ornithine lipid + 2-oxoglutarate + O2 = a 2-hydroxyornithine lipid + succinate + CO2
Glossary: an ornithine lipid = an Nα-[(3R)-3-(acyloxy)acyl]-L-ornithine
a 2-hydroxyornithine lipid = an Nα-[(3R)-3-(2-hydroxyacyloxy)acyl]-L-ornithine
Other name(s): olsC (gene name)
Systematic name: ornithine lipid,2-oxoglutarate:oxygen oxidoreductase (ester-linked acyl 2-hydroxylase)
Comments: The enzyme, characterized from the bacterium Rhizobium tropici, catalyses the hydroxylation of C-2 of the fatty acyl group that is ester-linked to the 3-hydroxy position of the amide-linked fatty acid.
