Regulation of phosphatidylinositol kinase activity in Saccharomyces cerevisiae.
The effects of growth phase and carbon source on membrane-associated phosphatidylinositol kinase in cell extracts of Saccharomyces cerevisiae were examined. Phosphatidylinositol kinase activity increased 2- and 2.5-fold in glucose- and glycerol-grown cells, respectively, in the stationary phase as compared with the exponential phase of growth. The increase in phosphatidylinositol kinase activit...
متن کاملA study of the regulation and function of Fablp, a phosphatidylinositol 3-phosphate 5 kinase in Saccharomyces cerevisiae
The Saccharomyces cerevisiae protein Fablp is the archetypal type III phosphatidyl inositol phosphate kinase. This family of enzymes is universal to all eukaryotes and is responsible for the synthesis of phosphatidylinositol 3,5-bisphosphate from phosphatidylinositol 3phosphate. In S. cerevisiae, Fablp regulates a number of cellular processes via the production of phosphatidylinositol 3,5-bisph...
متن کاملSaccharomyces cerevisiae sec59 cells are deficient in dolichol kinase activity.
The temperature-sensitive Saccharomyces cerevisiae mutant sec59 accumulates inactive and incompletely glycosylated protein precursors in its endoplasmic reticulum at the restrictive temperature. O-mannosylation and glycosyl phosphatidylinositol membrane anchoring of protein are also abolished, consistent with a deficiency in dolichyl phosphate mannose. Membranes prepared from sec59 cells that h...
متن کاملRegulation of the PIS1-encoded phosphatidylinositol synthase in Saccharomyces cerevisiae by zinc.
In the yeast Saccharomyces cerevisiae, the mineral zinc is essential for growth and metabolism. Depletion of zinc from the growth medium of wild type cells results in changes in phospholipid metabolism, including an increase in phosphatidylinositol content (Iwanyshyn, W. M., Han, G.-S., and Carman, G. M. (2004) J. Biol. Chem. 279, 21976-21983). We examined the effects of zinc depletion on the r...
متن کاملRegulation of cation balance in Saccharomyces cerevisiae.
All living organisms require nutrient minerals for growth and have developed mechanisms to acquire, utilize, and store nutrient minerals effectively. In the aqueous cellular environment, these elements exist as charged ions that, together with protons and hydroxide ions, facilitate biochemical reactions and establish the electrochemical gradients across membranes that drive cellular processes s...
