Yeast sphingolipids do not need to contain very long chain fatty acids.
Synthesis of VLCFAs (very long chain fatty acids) and biosynthesis of DHS (dihydrosphingosine) both are of vital importance for Saccharomyces cerevisiae. The bulk of VLCFAs and DHS are used for ceramide synthesis by the Lag1p (longevity-assurance gene 1)/Lac1p (longevity-assurance gene cognate 1)/Lip1p (Lag1p/Lac1p interacting protein) ceramide synthase. LAG1 and LAC1 are redundant but LIP1 is ...
متن کاملMetabolism of Very Long-Chain Fatty Acids: Genes and Pathophysiology
Fatty acids (FAs) are highly diverse in terms of carbon (C) chain-length and number of double bonds. FAs with C>20 are called very long-chain fatty acids (VLCFAs). VLCFAs are found not only as constituents of cellular lipids such as sphingolipids and glycerophospholipids but also as precursors of lipid mediators. Our understanding on the function of VLCFAs is growing in parallel with the identi...
متن کاملChain elongation, 20hydroxylation, and decarboxylation of long chain fatty acids by yeast.
Chain elongation and 2-hydroxylation pathways, which are specific for very long chain fatty acids ( >C&), have been found in the yeast, Candida utitis. The chain elongation system acts specifically on fatty acids of chain length C2,, to CZ4; there is no detectable elongation of Cl* and only trace . . . actrvrty with C&,. The product of the elongation enzyme or enzymes is C& when Co, C&, or C24 ...
متن کاملBinding of long-chain fatty acids
We have studied the binding of long-chain free fatty acids (FFA) to crystalline bovine serum albumin (BSA) that had been extracted with charcoal to remove endogenous fatty acids. The data were analyzed in terms of a model consisting of six high-energy binding sites and a large number of
متن کاملA Role for Very-Long-Chain Fatty Acids in Furrow Ingression during Cytokinesis in Drosophila Spermatocytes
Cell shape and membrane remodeling rely on regulated interactions between the lipid bilayer and cytoskeletal arrays at the cell cortex. During cytokinesis, animal cells build an actomyosin ring anchored to the plasma membrane at the equatorial cortex. Ring constriction coupled to plasma-membrane ingression separates the two daughter cells. Plasma-membrane lipids influence membrane biophysical p...
