Cloning, nucleotide sequence, and expression of one of two genes coding for yeast elongation factor 1 alpha.
One gene coding for yeast cytoplasmic elongation factor 1 alpha (EF-1 alpha) was isolated by colony hybridization using a cDNA probe prepared from purified EF-1 alpha mRNA. A recombinant plasmid, pLB1, with a 6-kilobase yeast DNA insert, was found by hybrid selection and translation experiments to carry the entire gene. The nucleotide sequence of the gene with its 5'- and 3'-flanking regions wa...
متن کاملMutations in elongation factor EF-1 alpha affect the frequency of frameshifting and amino acid misincorporation in Saccharomyces cerevisiae.
A mutational analysis of the eukaryotic elongation factor EF-1 alpha indicates that this protein functions to limit the frequency of errors during genetic code translation. We found that both amino acid misincorporation and reading frame errors are controlled by EF-1 alpha. In order to examine the function of this protein, the TEF2 gene, which encodes EF-1 alpha in Saccharomyces cerevisiae, was...
متن کاملTwo forms of elongation factor 1 alpha (EF-1 alpha O and 42Sp50), present in oocytes, but absent in somatic cells of Xenopus laevis
We have purified and partially sequenced the EF-1 alpha protein from Xenopus laevis oocytes (EF-1 alpha O). We show that the two cDNA clones isolated by Coppared et al. (Coppard, N. J., K. Poulsen, H. O. Madsen, J. Frydenberg, and B. F. C. Clark. 1991. J. Cell Biol. 112:237-243) do not encode 42Sp50, as claimed by these authors, but two very similar forms of EF-1 alpha O (EF-1 alpha O and EF-1 ...
متن کاملNucleotide sequence of Mycobacterium leprae elongation factor (EF-Tu) gene.
The elongation factor EF-Tu is essential in bacterial translation and has sequences which are highly conserved even in phylogenetically distant bacteria. This allowed us to show that Gram negative bacteria had two copies of the tuf gene whereas most Gram positive bacteria including Mycobacteria had one copy of this gene (1). The agent of leprosy, Mycobacterium leprae, has been isolated from nat...
متن کاملThe Effect of Aerobic Training on Tumor Necrosis Factor alpha, Hypoxia-Inducible Factor-1 alpha & Vascular Endothelial Growth Factor Gene Expression in Cardiac Tissue of Diabetic Rats
Objective: The goal of this research was to determine the influence of 4 weeks aerobic training on gene expression of tumor necrosis factor alpha (TNF-α), hypoxia-inducible factor-1 alpha (HIF-1α) and vascular endothelial growth factor (VEGF) in the cardiac tissue of diabetic rats. Materials and Methods: In an experimental study, 30 male wistar rats were partitioned into three groups (n=10), d...
