Interaction of mitochondrial elongation factor Tu with aminoacyl-tRNA and elongation factor Ts.
Elongation factor (EF) Tu promotes the binding of aminoacyl-tRNA (aa-tRNA) to the acceptor site of the ribosome. This process requires the formation of a ternary complex (EF-Tu.GTP.aa-tRNA). EF-Tu is released from the ribosome as an EF-Tu.GDP complex. Exchange of GDP for GTP is carried out through the formation of a complex with EF-Ts (EF-Tu.Ts). Mammalian mitochondrial EF-Tu (EF-Tu(mt)) differ...
متن کاملDoc toxin is a kinase that inactivates elongation factor Tu.
The Doc toxin from bacteriophage P1 (of the phd-doc toxin-antitoxin system) has served as a model for the family of Doc toxins, many of which are harbored in the genomes of pathogens. We have shown previously that the mode of action of this toxin is distinct from the majority derived from toxin-antitoxin systems: it does not cleave RNA; in fact P1 Doc expression leads to mRNA stabilization. How...
متن کاملEngineering the elongation factor Tu for efficient selenoprotein synthesis
Selenocysteine (Sec) is naturally co-translationally incorporated into proteins by recoding the UGA opal codon with a specialized elongation factor (SelB in bacteria) and an RNA structural signal (SECIS element). We have recently developed a SECIS-free selenoprotein synthesis system that site-specifically--using the UAG amber codon--inserts Sec depending on the elongation factor Tu (EF-Tu). Her...
متن کاملTranslation elongation factor Tu cleaved by a phage-exclusion system.
Bacteriophage T4 multiples poorly in Escherichia coli strains carrying the defective prophage, e14; the e14 prophage contains the lit gene for late inhibitor of T4 in E. coli. The exclusion is caused by the interaction of the e14-encoded protein, Lit, with a short RNA or polypeptide sequence encoded by gol from within the major head protein gene of T4. The interaction between Lit and the gol pr...
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...
