Direct comparison of nick-joining activity of the nucleic acid ligases from bacteriophage T4 [PDF]

open access: yes, 2006
The genome of bacteriophage T4 encodes three polynucleotide ligases, which seal the backbone of nucleic acids during infection of host bacteria. The T4Dnl (T4 DNA ligase) and two RNA ligases [T4Rnl1 (T4 RNA ligase 1) and T4Rnl2] join a diverse array of ...

Conformational analysis of nucleic acids revisited: Curves+ [PDF]

open access: yesNucleic Acids Research, 2009
We describe Curves+, a new nucleic acid conformational analysis program which is applicable to a wide range of nucleic acid structures, including those with up to four strands and with either canonical or modified bases and backbones. The program is algorithmically simpler and computationally much faster than the earlier Curves approach, although it ...

Protein-DNA interactions: statistical analysis of interatomic contacts in major and minor grooves

open access: yesВавиловский журнал генетики и селекции, 2018
The interactions between protein and DNA in essence underlie all processes in a living cell. Understanding the principles of specific recognition of DNA sites will open the way to understand how these processes are controlled and to interfere in their ...

Structure of an archaeal PCNA1-PCNA2-FEN1 complex: elucidating PCNA subunit and client enzyme specificity. [PDF]

open access: yes, 2006
The archaeal/eukaryotic proliferating cell nuclear antigen (PCNA) toroidal clamp interacts with a host of DNA modifying enzymes, providing a stable anchorage and enhancing their respective processivities.

Solution conformation of 2-aminopurine dinucleotide determined by ultraviolet two-dimensional fluorescence spectroscopy

open access: yesNew Journal of Physics, 2013
We have observed the conformation-dependent electronic coupling between the monomeric subunits of a dinucleotide of 2-aminopurine (2-AP), a fluorescent analogue of the nucleic acid base adenine.

Replication enhancer elements within the open reading frame of tick-borne encephalitis virus and their evolution within the Flavivirus genus [PDF]

open access: yes, 2011
We provide experimental evidence of a replication enhancer element (REE) within the capsid gene of tick-borne encephalitis virus (TBEV, genus Flavivirus).

High intrinsic hydrolytic activity of cyanobacterial RNA polymerase compensates for the absence of transcription proofreading factors [PDF]

open access: yes, 2020
The vast majority of organisms possess transcription elongation factors, the functionally similar bacterial Gre and eukaryotic/archaeal TFIIS/TFS. Their main cellular functions are to proofread errors of transcription and to restart elongation via ...

T7 RNA polymerase functions in vitro without clustering. [PDF]

open access: yesPLoS ONE, 2012
Many nucleic acid polymerases function in clusters known as factories. We investigate whether the RNA polymerase (RNAP) of phage T7 also clusters when active.

Structural basis for the sequence-specific RNA-recognition mechanism of human CUG-BP1 RRM3 [PDF]

open access: yes, 2009
The CUG-binding protein 1 (CUG-BP1) is a member of the CUG-BP1 and ETR-like factors (CELF) family or the Bruno-like family and is involved in the control of splicing, translation and mRNA degradation.
