Lipid Biosynthesis Inhibitors

Five classes of herbicides (carbamothioates, chloroacetamides, substituted pyridazinones, cyclohexanediones, and aryloxyphenoxypropionic acids) have been reported to inhibit lipid biosynthesis in higher plants. Carbamothioates impair the synthesis of surface lipids (waxes, cutin, suberin). These effects have been attributed to the ability of this herbicide class to inhibit one or more acyl-CoA ...

Complex Lipid Biosynthesis: Phospholipid Synthesis

T o analyse the involvement of the plastidial lysophosphatidylcholine (lyso-PC) acyltransferase in the import of the extraplastidial lipid precursors required for eukaryotic plastid lipid synthesis, we plan to obtain transgenic plants. Since no sequence of lyso-PC acyltransferase is known, the purification of this enzyme has been undertaken to establish its sequence. First we determined the con...

Complex Lipid Biosynthesis: Phospholipid Synthesis

Fluorescent phosphatidic acid and phosphatidylcholine were used to characterize lipid-transport pathways into lipid bodies in an oleaginous fungus, Mortierella ramanniana var. angulispora. Several characteristics of the lipid transport such as temperature dependence and ATP dependence were evaluated. The transport depicted by these fluorescent lipids was consistent with metabolism of radiolabel...

Fractionation of hydrogen isotopes in lipid biosynthesis

Isotopic compositions of carbon-bound hydrogen in individual compounds from eight di€erent organisms were measured using isotope-ratio-monitoring gas chromatography±mass spectrometry. This technique is capable of measuring D/H ratios at natural abundance in individual lipids yielding as little as 20 nmol of H2, and is applicable to a wide range of compounds including hydrocarbons, sterols, and ...
