具有完整细胞器的酿酒酵母通过高等真核生物中常见的途径合成膜磷脂。酵母中的磷脂合成响应于多种生长条件(例如,肌醇补充、锌缺乏和生长阶段)通过遗传(例如,转录激活和抑制)和生物化学(例如,活性调节和定位)机制。磷脂酸(PA),其细胞水平由关键磷脂合成酶的活性控制,在磷脂合成基因的转录调控中起着核心作用。除了基因表达的调节之外,关键磷脂合成催化和调节蛋白的磷酸化控制磷脂前体和产物的代谢。
The yeast Saccharomyces cerevisiae, with its full complement of organelles, synthesizes membrane phospholipids by pathways that are generally common to those found in higher eukaryotes. Phospholipid synthesis in yeast is regulated in response to a variety of growth conditions (e.g., inositol supplementation, zinc depletion, and growth stage) by a coordination of genetic (e.g., transcriptional activation and repression) and biochemical (e.g., activity modulation and localization) mechanisms. Phosphatidate (PA), whose cellular levels are controlled by the activities of key phospholipid synthesis enzymes, plays a central role in the transcriptional regulation of phospholipid synthesis genes. In addition to the regulation of gene expression, phosphorylation of key phospholipid synthesis catalytic and regulatory proteins controls the metabolism of phospholipid precursors and products.
