Phosphatidate phosphatase plays role in zinc-mediated regulation of phospholipid synthesis in yeast.
In the yeast Saccharomyces cerevisiae, the synthesis of phospholipids is coordinately regulated by mechanisms that control the homeostasis of the essential mineral zinc (Carman, G.M., and Han, G. S. (2007) Regulation of phospholipid synthesis in Saccharomyces cerevisiae by zinc depletion. Biochim. Biophys. Acta 1771, 322-330; Eide, D. J. (2009) Homeostatic and adaptive responses to zinc deficie...
متن کاملRegulation of phospholipid synthesis in yeast by zinc.
The yeast Saccharomyces cerevisiae has the ability to cope with a variety of stress conditions (e.g. zinc deficiency) by regulating the expression of enzyme activities including those involved with phospholipid synthesis. Zinc is an essential mineral required for the growth and metabolism of S. cerevisiae. Depletion of zinc from the growth medium of wild-type cells results in alterations in pho...
متن کاملPhosphatidate phosphatase activity plays key role in protection against fatty acid-induced toxicity in yeast.
The PAH1-encoded phosphatidate (PA) phosphatase in Saccharomyces cerevisiae is a pivotal enzyme that produces diacylglycerol for the synthesis of triacylglycerol (TAG) and simultaneously controls the level of PA used for phospholipid synthesis. Quantitative lipid analysis showed that the pah1Δ mutation caused a reduction in TAG mass and an elevation in the mass of phospholipids and free fatty a...

متن کاملYeast Pah1p phosphatidate phosphatase is regulated by proteasome-mediated degradation.
Yeast PAH1-encoded phosphatidate phosphatase is the enzyme responsible for the production of the diacylglycerol used for the synthesis of triacylglycerol that accumulates in the stationary phase of growth. Paradoxically, the growth phase-mediated inductions of PAH1 and phosphatidate phosphatase activity do not correlate with the amount of Pah1p; enzyme abundance declined in a growth phase-depen...
