Vid30 complex participation in the degradation of CDC25 in yeast and their role in Ras/ cAMP/ PKA pathway

Background: Unicellular organisms such as Saccharomyces cerevisiae in its total life cycle is exposed to diverse and changing nutrient conditions. Thus, in order to survive and achieve a competitive advantage, it has adapted itself such that it not only uses the wide range of available nutrient sources but also the sources that are nutrient rich. It mainly uses fructose and glucose by rapidly fermenting to alcohol. In response to these nutrient conditions, the intracellular trafficking transcription and turnover of protein from nutrient transporters (e.g. Hxts) get regulated. Therefore, when the availability of the glucose increases, the expression of low- ...

Introduction

Baker's yeast is the ordinary term known of certain generic classes of yeast normally utilized as a baking agent in bread and bakery commodities production, wherein it translates the fermentable glucose and sucrose otherwise found in dough into two products that are carbon dioxide and ethanol. Scientifically, this yeast is categorized under species Saccharomyces cerevisiae (Sonnleitner, 2006). This is the same species frequently employed in the fermentation of alcohol hence the tag brewer's yeast is also accorded to it. In this experiment, we attempted to produce yeast through the process of fermentation (Kristiansen, 2004). The fermentation process is powerfully aimed ...
