Novel inhibition of archaeal family-D DNA polymerase by uracil. [PDF]

, 2013
International audienceArchaeal family-D DNA polymerase is inhibited by the presence of uracil in DNA template strands. When the enzyme encounters uracil, following three parameters change: DNA binding increases roughly 2-fold, the rate of polymerization ...

Characterization of B Cell Responses in Rainbow Trout (Oncorhynchus Mykiss) Affected by Red Mark Syndrome

Advanced Science, EarlyView.
This study extensively characterizes the B cell response of rainbow trout (Oncorhynchus mykiss) in response to red mark syndrome (RMS). This disease, suspected to be caused by a Midichloria‐like organism (MLO), induces skin lesions in the infected animals, characterized by a massive influx of IgM+ B cells.

Chicken MBD4 Regulates Immunoglobulin Diversification by Somatic Hypermutation

Frontiers in Immunology, 2019
Immunoglobulin (Ig) diversification occurs via somatic hypermutation (SHM) and class switch recombination (CSR), and is initiated by activation-induced deaminase (AID), which converts cytosine to uracil.

Plasmonic Molecular Entrapment for Label‐Free Methylated DNA Detection and Machine‐Learning Assisted Quantification

Advanced Science, EarlyView.
Plasmonic molecular entrapment (PME) is label‐free detection and quantification method for DNA methylation. This technique provides direct hotspot site generation around target analytes, overcoming mismatch geometrical properties. The PME demonstrates superior SERS performance and quantification capability, offering promising potential for epigenetic ...

Raman depolarization ratios in RNA and DNA are sensitive for sugar-base coupling [PDF]

, 1995
Polarized and depolarized Raman spectra are obtained for a number of synthetic polynucleotides containing adenine, uracil, and thymine bases. The depolarization ratios are determined by two methods: (1) by dividing the -spectrum by the -spectrum and (2 ...

Engineering Adenine Deaminase TadA for Precise and PAM‐Flexible Point Mutagenesis and Gradient‐Tuning Endogenous Protein Design

Advanced Science, EarlyView.
Base editing enables precise nucleotide substitutions but limited by bystander editing. This study engineers plant base editors by fusing optimized TadA variants with PAM‐flexible SpRY nickase, enabling A‐to‐G, C‐to‐T, and dual‐base conversions in a highly condensed window (≤3 nucleotides). Additionally, TadDBE (TadA Dual‐Base Editor)‐mediated directed

Low energy electron scattering from DNA and RNA bases: shape resonances and radiation damage

, 2005
Calculations are carried out to determine elastic scattering cross sections and resonance energies for low energy electron impact on uracil and on each of the DNA bases (thymine, cytosine, adenine, guanine), for isolated molecules in their equilibrium ...
