Purification of Saccharomyces cerevisiae eIF4E/eIF4G/Pab1p Complex with Capped mRNA
Protein synthesis is one of the most complex cellular processes, involving numerous translation components that interact in multiple sequential steps. The most complex stage in protein synthesis is the initiation process. The basal set of factors required for translation initiation has been determined, and biochemical, genetic, and structural studies are now beginning to reveal details of their...
متن کاملPurification 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...
متن کاملmRNA-decapping enzyme from Saccharomyces cerevisiae: purification and unique specificity for long RNA chains.
An enzyme that hydrolyzes one PPi bond of the cap structure of mRNA, yielding m7GDP and 5'-p RNA was purified from Saccharomyces cerevisiae to a stage suitable for characterization. The specificity of the enzyme was studied, using both yeast mRNA and synthetic RNAs labeled in the cap structure. A synthetic capped RNA (540 nucleotides) was not reduced in size, while as much as 80% was decapped. ...

متن کاملPurification and characterization of CDP-diacylglycerol synthase from Saccharomyces cerevisiae.
The membrane-associated phospholipid biosynthetic enzyme CDP-diacylglycerol synthase (CTP:phosphatidate cytidylyltransferase, EC 2.7.7.41) was purified 2,300-fold from Saccharomyces cerevisiae. The purification procedure included Triton X-100 solubilization of mitochondrial membranes, CDP-diacylglycerol-Sepharose affinity chromatography, and hydroxylapatite chromatography. The procedure resulte...
