| pubmed-article:15157452 | pubmed:abstractText | Most of the enzymes and genes required for lipid biosynthesis and degradation in the budding yeast Saccharomyces cerevisiae have now been identified and the global mechanisms that regulate their activity are being established. Synthesis of phospholipids is restricted to specific subcellular compartments, and the lipids migrate from their site of formation to their final destination. In addition to synthesis, remodelling and degradation of phospholipids controls the content of the lipid portion of cellular membranes, while highly specific phospholipases catalyse the release of lipid-based second messengers. In this review, we describe the current understanding of the organization and regulation of phospholipid metabolism in yeast, and discuss the mechanisms that have been proposed for intracellular lipid transport. | lld:pubmed |
