A Glucokinase from Saccharomyces cerevisiae

Saccharomyces cerevisiae

Yeast prions are infectious proteins that spread exclusively by mating. The frequency of prions in the wild therefore largely reflects the rate of spread by mating counterbalanced by prion growth slowing effects in the host. We recently showed that the frequency of outcross mating is about 1% of mitotic doublings with 23-46% of total matings being outcrosses. These findings imply that even the ...

Production of Single Cell Protein from Sugarcane Bagasse by Saccharomyces cerevisiae in Tray Bioreactor

In this study, solid state fermentation (SSF) was carried out to produce single cell protein (SCP) from sugarcane bagasse using Saccharomyces cerevisiae. The SSF experiment were performed in a tray bioreactor. The influence of several parameters including extraction buffer, initial moisture content of substrate, fermentation time, relative humidity in bioreactor, the bioreactor temperature and ...

Kinetics of Phosphomevalonate Kinase from Saccharomyces cerevisiae

The mevalonate-based isoprenoid biosynthetic pathway is responsible for producing cholesterol in humans and is used commercially to produce drugs, chemicals, and fuels. Heterologous expression of this pathway in Escherichia coli has enabled high-level production of the antimalarial drug artemisinin and the proposed biofuel bisabolane. Understanding the kinetics of the enzymes in the biosyntheti...

Purification of Active TFIID from Saccharomyces cerevisiae

The basal transcription factor TFIID is composed of the TATA-binding protein (TBP) and 14 TBP-associated factors (TAFs). Although TBP alone binds to the TATA box of DNA and supports basal transcription, the TAFs have essential functions that remain poorly defined. In order to study its properties, TFIID was purified from Saccharomyces cerevisiae using a newly developed affinity tag. Analysis of...
