Regulation of phosphatidate phosphatase activity from the yeast Saccharomyces cerevisiae by sphingoid bases.
The regulation of Saccharomyces cerevisiae membrane-associated phosphatidate phosphatase (3-sn-phosphatidate phosphohydrolase, EC 3.1.3.4) activity by sphingoid bases was examined using Triton X-100/lipid-mixed micelles. Sphingosine, phytosphingosine, and sphinganine inhibited purified preparations of the 104- and 45-kDa forms of phosphatidate phosphatase in a dose-dependent manner. The structu...
متن کاملCharacterization of Encapsulated Berberine in Yeast Cells of Saccharomyces cerevisiae
Berberine was loaded in yeast cells of Saccharomyces cerevisiaeas a novel pharmaceutical carrier to improve the treatment ofmany diseases. The yeast-encapsulated active materialsshowedhigh stability and bioavailability due to the enhanced solubility and sustained releasing. In this study, different characteristics of prepared berberine loaded yeast cells (loading capacity, release kinetic order...

متن کاملPhosphorylase phosphatase activity in Saccharomyces cerevisiae 257.
A phosphatase, active towards phosphorylase a and phosphorylated proteins casein and histone II-A, was isolated from Saccharomyces cerevisiae 257. The enzyme dephosphorylated glycogen phosphorylase from commercial yeast rendering it inactive. The protein phosphatase activity was not influenced by any metal ions. Phosphorylase phosphatase activity was slightly stimulated by p-nitrophenyl phospha...
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...
