A new RNA-RNA crosslinking reagent and its application to ribosomal 5S RNA.

open access: yesNucleic Acids Research, 1978
The synthesis of a new RNA specific bifunctional crosslinking reagent, 1.4-phenyl-diglyoxal, is described which reacts exclusively with guanosines. The properties of the crosslinked products enabled us to develop a straightforward method for identifying ...

Expansion segments in bacterial and archaeal 5S ribosomal RNAs [PDF]

open access: yesRNA, 2020
The large ribosomal RNAs of eukaryotes frequently contain expansion sequences that add to the size of the rRNAs but do not affect their overall structural layout and are compatible with major ribosomal function as an mRNA translation machine. The expansion of prokaryotic ribosomal RNAs is much less explored.

Organization and expression analysis of 5S and 45S ribosomal DNA clusters in autotetraploid Carassius auratus

open access: yesBMC Ecology and Evolution, 2021
Background Autotetraploid Carassius auratus (4n = 200, RRRR) (abbreviated as 4nRR) is derived from whole genome duplication of Carassius auratus red var. (2n = 100, RR) (abbreviated as RCC).

Evolutionary Dynamics of Multigene Families in Triportheus (Characiformes, Triportheidae): A Transposon Mediated Mechanism? [PDF]

open access: yes, 2020
Triportheus (Characiformes, Triportheidae) is a freshwater fish genus with 18 valid species. These fishes are widely distributed in the major river drainages of South America, having commercial importance in the fishing market, mainly in the Amazon basin.

Amplification and adaptation of centromeric repeats in polyploid switchgrass species. [PDF]

open access: yes, 2018
Centromeres in most higher eukaryotes are composed of long arrays of satellite repeats from a single satellite repeat family. Why centromeres are dominated by a single satellite repeat and how the satellite repeats originate and evolve are among the most

Traffic of interacting ribosomes: effects of single-machine mechano-chemistry on protein synthesis [PDF]

open access: yesPhysical Review E 75, 021902 (2007), 2006
Many ribosomes simultaneously move on the same messenger RNA (mRNA), each separately synthesizing the protein coded by the mRNA. Earlier models of ribosome traffic represent each ribosome by a ``self-propelled particle'' and capture the dynamics by an extension of the totally asymmetric simple exclusion process (TASEP).

Distinct ribosome maturation defects in yeast models of Diamond-Blackfan anemia and Shwachman-Diamond syndrome

open access: yesHaematologica, 2010
Background Diamond-Blackfan anemia and Shwachman-Diamond syndrome are inherited bone marrow failure syndromes linked to defects in ribosome synthesis.

Evolutionary changes in the higher order structure of the ribosomal 5S RNA

open access: yesNucleic Acids Res., 1987
Comparative studies have been undertaken on the higher order structure of ribosomal 5S RNAs from diverse origins. Competitive reassociation studies show that 5S RNA from either a eukaryote or archaebacterium will form a stable ribonucleoprotein complex ...

5S Ribosomal RNA data bank

open access: yesNucleic Acids Research, 1999
This paper presents the updated version of the data base of ribosomal 5S ribonucleic acids (5S rRNA) and their genes (5S rDNA). This edition of the data bank contains 1889 primary structures of 5S rRNA and 5S rDNA. These include 60 archaebacterial, 439 eubacterial, 63 plastid, 9 mitochondrial and 1318 eukaryotic sequences.
