Structure and stereochemistry of the base excision repair glycosylase MutY reveal a mechanism similar to retaining glycosidases. [PDF]

, 2015
MutY adenine glycosylases prevent DNA mutations by excising adenine from promutagenic 8-oxo-7,8-dihydroguanine (OG):A mismatches. Here, we describe structural features of the MutY active site bound to an azaribose transition state analog which indicate a

Nucleotides: Structure and Properties [PDF]

, 2005
Nucleotides consist of a nitrogen-containing base, a five-carbon sugar, and one or more phosphate groups. Cells contain many types of nucleotides, which play a central role in a wide variety of cellular processes, including metabolic regulation and the ...

DGR mutagenic transposition occurs via hypermutagenic reverse transcription primed by nicked template RNA. [PDF]

, 2017
Diversity-generating retroelements (DGRs) are molecular evolution machines that facilitate microbial adaptation to environmental changes. Hypervariation occurs via a mutagenic retrotransposition process from a template repeat (TR) to a variable repeat ...

Moderate exercise training promotes adaptations in coronary blood flow and adenosine production in normotensive rats

Clinics, 2011
OBJECTIVES: Aerobic exercise training prevents cardiovascular risks. Regular exercise promotes functional and structural adaptations that are associated with several cardiovascular benefits. The aim of this study is to investigate the effects of swimming

CRISPR/Cas9-Mediated Adenine Base Editing in Rice Genome

Rice Science, 2019
SUMMARY: Precise base editing is highly desired in plant functional genomic research and crop molecular breeding. In this study, we constructed a rice-codon optimized adenine base editor (ABE)-nCas9 tool that induced targeted A·T to G·C point mutation of

Defining the molecular mechanisms of the mitochondrial permeability transition through genetic manipulation of F-ATP synthase

Nature Communications, 2021
The nature of the mitochondrial permeability transition pore (PTP) is still under debate. Here, through genetically modified F-ATP synthase, the authors show that PTP formation can be mediated by F-ATP synthase or by adenine nucleotide translocator ...

Nucleotide specificity of the enzymatic and motile activities of dynein, kinesin, and heavy meromyosin. [PDF]

, 1991
The substrate specificities of dynein, kinesin, and myosin substrate turnover activity and cytoskeletal filament-driven translocation were examined using 15 ATP analogues.

Substrate Nucleotide-Determined Non-Templated Addition of Adenine by Taq DNA Polymerase: Implications for PCR-Based Genotyping and Cloning

BioTechniques, 1996
The Applied Biosystems PRISMTM fluorescence-based genotyping system as well as the Invitrogen TA Cloning® vector system are influenced by the tendency of Taq DNA polymerase to add an adenine nucleotide to the 3′ end of PCR products after extension ...

Attenuation of ischemic liver injury by prostaglandin E1 analogue, misoprostol, and prostaglandin I2 analogue, OP-41483 [PDF]

, 1998
Background: Prostaglandin has been reported to have protective effects against liver injury. Use of this agent in clinical settings, however, is limited because of drugrelated side effects.

Protocol for targeted modification of the rice genome using base editing

STAR Protocols, 2022
Summary: Base editing is a precision genome-editing approach that is widely utilized to generate single-nucleotide variants (SNVs) in genomes. Here, we present a protocol to perform targeted adenine (A)-to-guanine (G) substitution in rice using adenine ...
