Acetate utilization and macromolecular synthesis during sporulation of yeast.
Acetate utilization and macromolecule synthesis during sporulation (meiosis) of Saccharomyces cerevisiae were studied. When diploid cells are transferred from glucose nutrient medium to acetate sporulation medium at early stationary phase, respiration of the exogenously supplied acetate proceeds without any apparent lag. At the completion of ascospore development, 62% of the acetate carbon cons...

is too fast to be measured by the methods used. The second step, which involves the acylation of the enzyme and the concomitant liberation of pnitrophenol, is characterized by the rate constant k2= 3-15 sec.-'. The third step involves the liberation of acetate and reactivation of the enzyme; the rate of this reaction is defined by kI3= 0-0254 sec.-'. 2. The rate constant k2 for the second step ...
متن کاملHistological Changes in the Liver and Biochemical Parameters of Chickens Treated with Lead Acetate II
Background: Lead is one of the heavy metals that is persists in the environment and has destructive effects on various human tissues. We investigated the effects of lead on the histological features of liver and its enzymatic functions. Methods: Forty chickens were purchased and randomly divided into four groups. In addition to the normal feed, each group received different doses of lead aceta...
متن کاملBiochemical studies of bacterial sporulation and germination. XIX. Phosphate metabolism during sporulation.
Acid-soluble phosphate compounds represent about 25 % of the total phosphate of Bacillus megaferium vegetative cells, but only 7% of the total phosphate in dormant spores. In vegetative cells, 12 compounds make up 90% of the acidsoluble phosphate. These same compounds predominate throughout growth and early sporulation, although their relative amounts change during the process. One hour before ...
متن کاملBiochemical changes occurring during sporulation of Bacillus cereus. Inhibition of sporulation by alpha-picolinic acid.
The effects of nutritional and environmental conditions on sporulation and the properties of the spore have been extensively studied with the hope that these may provide a clue to the mechanism of dormancy and resistance of the bacterial endospore. However, there is no general agreement and our knowledge of these is still limited. The extensive literature dealing with the various aspects of spo...
