Biosynthesis of ornithine lipids in Rhizobium tropici CIAT899. The genes coding for OlsB and OlsA have been first identified in Sinorhizobium meliloti, whereas the gene encoding the OL hydroxylase OlsC has been described first in Rhizobium tropici. Here we describe that the hydroxylation introduced by OlsC is in the 2 position of the secondary fatty acid. We also describe the identification of the gene encoding the OL hydroxylase OlsE introducing a hydroxyl group in the ornithine moiety of OL. Lyso-ornithine lipid (LOL), ornithine lipid (OL).
