Because of its importance in decoding, its small size (～25 000 Da or 73-93 nucleotides) and its availability, tRNA became a favoured example of a nucleic acid molecule in the 1960s for both sequence determination and 3D-structural elucidation. The first primary structural determination of a ...
A transfer of flexibility to the corner of the tRNA molecule disrupts the G19-C56 tertiary interactions. Chemical mapping of the N3 position of cytosine 56 and analysis of self-splitting patterns of tRNAAsp substantiate such a correlation. 展开 ...
Since the central dogma was proposed in 1950, the main role attributed to RNA has been to act as the intermediate between DNA and protein synthesis. Yet, more than 70% of the genome is transcribed and just a small part codes for proteins1,2, which indicates that the majority of RNAs cou...

The ways in which an RNA molecule folds to form structures can be crucial to its function, and so methods for studying RNA structures make an important contribution to understanding transcriptomes. Experimental approaches in this field are being advanced
a crucial role in various cellular processes. There are two main types of RNA editing events: adenosine to inosine (A-to-I) editing, catalyzed by ADARs on double-stranded RNA or ADATs on tRNA, and cytosine to uridine (C-to-U) editing catalyzed by APOBECs. This article provides an ...
When represented in the three-dimensional structure of the tRNA Asp, it clearly appears that one side of the L-shaped tRNA molecule, that comprising the variable loop, is in contact with aspartyl-tRNA synthetase. In yeast tRNA Phe interacting with phenylalanyl-tRNA synthetase, the distribution of...
Tertiary Structure of Ribonuclease A model is proposed of the polypeptide chain in bovine pancreatic ribonuclease based on a 2 electron density map involving 7,294 reflexions and data from seven heavy atom derivatives. The molecule seems to be roughly kidney shaped with ... G Kartha,J Bello,D ...
The crystal structure of catalase-peroxidase from PCC7942 (KatG) was solved by molecular replacement and refined to an of 16.8% and an of 20.6% at 2.2 Å resolution. The asymmetric unit consisted of only one subunit of the catalase-peroxidase molecule, including a protoporphyrin IX haem moiety...
