  • Title: Definition of total biosynthesis pathway of taurolipids in Tetrahymena cells.
    Author: Kaya K, Sano T.
    Journal: Biochim Biophys Acta; 1991 Jun 19; 1084(1):101-4. PubMed ID: 2054373.
    Abstract:
    Taurine-combined fatty acids were found in the lipotaurine fraction of cells of Tetrahymena thermophila. Taurine and fatty acid moieties of the compounds were identified by nuclear magnetic resonance and gas chromatography-mass spectrometry, respectively. The molar ratio of fatty acid methyl esters and taurine in the hydrolysate of the lipotaurine fraction by methanolic hydrochloric acid hydrolysis, was 1.06:1.00. From the results, the structures of six taurine-combined fatty acids including lipotaurine in the fraction were identified. These structures suggest that the compounds are precursors of lipotaurine as an intermediate of taurolipids biosynthesis, and lipotaurine is biosynthesized via 2-(octadecanoylamino)ethanesulfonic acid and 2-(7-hydroxy-13-octadecenoylamino)ethanesulfonic acid. From the results of the present study and our previous studies, the total biosynthesis pathway of taurolipids is defined.
