Effect of UV Light on RNA-Directed DNA Polymerase Activity of Murine Oncornaviruses [PDF]

open access: yesJournal of Virology, 1975
The UV inactivation of RNA-directed DNA polymerase activity of Rauscher leukemia virus was shown to be due to damage to the protein. The UV dose resulting in 37% survival of viral polymerase activity at 254 nm was 2.4 × 10 4 to 3.1 × 10 4 ergs/mm 2 .

Heterochromatic siRNAs and DDM1 independently silence aberrant 5S rDNA transcripts in Arabidopsis. [PDF]

open access: yesPLoS ONE, 2009
5S ribosomal RNA gene repeats are arranged in heterochromatic arrays (5S rDNA) situated near the centromeres of Arabidopsis chromosomes. The chromatin remodeling factor DDM1 is known to maintain 5S rDNA methylation patterns while silencing transcription ...

Genomic analysis of Poxviridae and exploring qualified gene sequences for phylogenetics

open access: yesComputational and Structural Biotechnology Journal, 2021
The members of the Poxviridae family are globally distributed all over the world and can cause infectious diseases. Although genome sequences are publicly available for representative isolates of all genera, studies on the criteria for genome-based ...

Morphological and Molecular Characterization of Pseudocercospora chionanthi-retusi Causing Leaf Spot on Chionanthus retusus in Korea [PDF]

open access: yesResearch in Plant Disease, 2022
Leaves of Chionanthus retusus were found to be damaged by leaf spot disease associated with a fungus in Iksan, Korea. Leaf spots were angular to irregular, vein-limited, scattered, 1–8 mm diameter, brownish-gray to dark brown when dry, with heavy ...

RNA-directed DNA polymerase from particles released by normal goose cells [PDF]

open access: yesJournal of Virology, 1979
Cells from a goose embryo were shown to release particle-associated RNA-directed DNA polymerase and RNase H activities that required the presence of Nonidet P-40 for detection. The particles were not infectious and did not have endogenous DNA synthesis.

Unwinding-like activity associated with avian retrovirus RNA-directed DNA polymerase [PDF]

open access: yesJournal of Virology, 1978
The avian retrovirus RNA-directed DNA polymerase contains an activity that is capable of removing hydrogen bonds from duplex nucleic acid molecules. This "unwinding-like" activity appears to be specific in its action, affecting RNA.DNA and DNA.DNA duplex molecules but not RNA.RNA duplexes.

Pol IV-Dependent siRNA Production is Reduced in Brassica rapa

open access: yesBiology, 2013
Plants produce a diverse array of small RNA molecules capable of gene regulation, including Pol IV-dependent short interfering (p4-si)RNAs that trigger transcriptional gene silencing.

Dielectricity of a molecularly crowded solution accelerates NTP misincorporation during RNA-dependent RNA polymerization by T7 RNA polymerase

open access: yesScientific Reports, 2022
In biological systems, the synthesis of nucleic acids, such as DNA and RNA, is catalyzed by enzymes in various aqueous solutions. However, substrate specificity is derived from the chemical properties of the residues, which implies that perturbations of ...

Extent of Transcription of Mouse Sarcoma-Leukemia Virus by RNA-Directed DNA Polymerase [PDF]

open access: yesProceedings of the National Academy of Sciences, 1974
The DNA product obtained from the endogenous RNA-directed DNA polymerase (deoxynucleosidetriphosphate:DNA deoxynucleotidyltransferase, EC 2.7.7.7) reaction of the Moloney sarcoma:leukemia viruses produced by the 78 A-1 cell line was analyzed and characterized.

Inhibitors of HIV-1 Reverse Transcriptase—Associated Ribonuclease H Activity

open access: yesBiology, 2012
HIV-1 enzyme reverse transcriptase (RT) is a major target for antiviral drug development, with over half of current FDA-approved therapeutics against HIV infection targeting the DNA polymerase activity of this enzyme. HIV-1 RT is a multifunctional enzyme
