The GA motif: an RNA element common to bacterial antitermination systems, rRNA, and eukaryotic RNAs.
Two different transcription termination control mechanisms, the T box and S box systems, are used to regulate transcription of many bacterial aminoacyl-tRNA synthetase, amino acid biosynthesis, and amino acid transport genes. Both of these regulatory mechanisms involve an untranslated mRNA leader region capable of adopting alternate structural conformations that result in transcription terminat...
متن کاملHuman intron-encoded AluACA RNAs and telomerase RNA share a common element promoting RNA accumulation
Mammalian cells express hundreds of intron-encoded box H/ACA RNAs which fold into a common hairpin-hinge-hairpin-tail structure, interact with 4 evolutionarily conserved proteins, dyskerin, Nop10, Nhp2 and Gar1, and function mainly in RNA pseudouridylation. The human telomerase H/ACA RNA (hTR) directs telomeric DNA synthesis and it carries a 5'-terminal domain encompassing the telomeric templat...
متن کاملNMR structure and dynamics of an RNA motif common to the spliceosome branch-point helix and the RNA-binding site for phage GA coat protein.
The RNA molecules that make up the spliceosome branch-point helix and the binding site for phage GA coat protein share a secondary structure motif in which two consecutive adenine residues occupy the strand opposite a single uridine, creating the potential to form one of two different A.U base pairs while leaving the other adenine unpaired or bulged. During the splicing of introns out of pre-mR...
متن کاملSubstrate specificity of bacterial oligosaccharyltransferase suggests a common transfer mechanism for the bacterial and eukaryotic systems.
The PglB oligosaccharyltransferase (OTase) of Campylobacter jejuni can be functionally expressed in Escherichia coli, and its relaxed oligosaccharide substrate specificity allows the transfer of different glycans from the lipid carrier undecaprenyl pyrophosphate to an acceptor protein. To investigate the substrate specificity of PglB, we tested the transfer of a set of lipid-linked polysacchari...
متن کاملrRNA antitermination functions with heat shock promoters.
Transcription antitermination in the rRNA operons of Escherichia coli requires a unique nucleic acid sequence that serves as a signal for modification of the elongating RNA polymerase, making it resistant to Rho-dependent termination. We examined the antitermination ability of RNA polymerase elongation complexes that had initiated at three different heat shock promoters, dnaK, groE, and clpB, a...
