Nucleotide 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 کاملCloning, 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 کاملInteraction of the isolated domain II/III of Thermus thermophilus elongation factor Tu with the nucleotide exchange factor EF-Ts.
The middle and C-terminal domain (domain II/III) of elongation factor Tu from Thermus thermophilus lacking the GTP/GDP binding domain have been prepared by treating nucleotide-free protein with Staphylococcus aureus V8 protease. The isolated domain II/III of EF-Tu has a compact structure and high resistance against tryptic treatment and thermal denaturation. As demonstrated by circular dichrois...
متن کاملIdentification of a cDNA sequence coding for kruppellike factor 2b (Klf2b) from the skin mucosa of common carp (Cyprinus carpio)
Kruppel-like factors (Klfs) are a highly related zinc-finger family of transcription factors implicated inthe regulation of the eukaryotic cellular growth and differentiation of a diverse set of cells in mammal. UsingRT-PCR technique, a 456 bp cDNA fragment encoding N-terminus part of a Klf2b was isolated from the skinmucosa of common carp (Cyprinus carpio) using two degenerative oligonucleotid...
متن کاملGuanine-nucleotide exchange on ribosome-bound elongation factor G initiates the translocation of tRNAs
BACKGROUND During the translation of mRNA into polypeptide, elongation factor G (EF-G) catalyzes the translocation of peptidyl-tRNA from the A site to the P site of the ribosome. According to the 'classical' model, EF-G in the GTP-bound form promotes translocation, while hydrolysis of the bound GTP promotes dissociation of the factor from the post-translocation ribosome. According to a more rec...
