RESUMO
Two-dimensional thin-layer chromatography revealed that Cytophaga johnsonae contains at least 10 kinds of lipid, 2 of which are phospholipids, namely, phosphatidylethanolamine and phosphatidylcholine. One of the remaining lipids is a novel lipid that contains an amino acid. The structure of this unusual lipid (lipoamino acid) was resolved by chemical and physicochemical methods. The fatty acyl moiety of this lipid was diverse. The structure of the major molecular species of the lipid was determined as iso-3-hydroxy heptadecanoic acid, amide linked to glycine and esterified to isopentadecanoic acid. This type of glycine-containing lipid is a novel biological material which we have called cytolipin, basing this nomenclature on the genus of the bacterium. This is the first report of the lipid composition of C. johnsonae.
