Isolation and physical properties of the DNA‐directed RNA polymerase from Thermus thermophilus HB8 [PDF]
The DNA‐directed RNA polymerase from the extremely thermophilic eubacterium Thermus thermophilus HB8 was purified employing a new and rapid method. The subunit pattern of the enzyme, analyzed by SDS gel electrophoresis, was interpreted as: 140 kDa and 170 kDa for β and β′, 40 kDa for α and 92 kDa for ó.

Primer Extension Reactions for the PCR- based α- complementation Assay
The PCR- based- α- complementation assay is an effective technique to measure the fidelity of polymerases, especially RNA-dependent RNA polymerases (RDRP) and Reverse Transcriptases (RT). It has been successfully employed to determine the fidelity of the

Kinetic analysis of an efficient DNA-dependent TNA polymerase. [PDF]
alpha-l-Threofuranosyl nucleoside triphosphates (tNTPs) are tetrafuranose nucleoside derivatives and potential progenitors of present-day beta-d-2'-deoxyribofuranosyl nucleoside triphosphates (dNTPs).

Cotranscriptional kinetic folding of RNA secondary structures including pseudoknots [PDF]
Computational prediction of RNA structures is an important problem in computational structural biology. Studies of RNA structure formation often assume that the process starts from a fully synthesized sequence. Experimental evidence, however, has shown that RNA folds concurrently with its elongation.

DNA-directed DNA Polymerase Activity in Oncogenic RNA Viruses
Besides having RNA-dependent DNA polymerase activity, oncogenic RNA viruses possess a DNA-directed DNA polymerase which is distinguished from previously described enzymes of this type in preferring double-stranded DNA as template and yielding a principally double-stranded product.

Antibodies to the DNA-directed RNA polymerase II subunit RPB1 occur with highest frequency in centenarians [PDF]
BACKGROUND: Recently, phage display technology has made it possible to define the circulating repertoire of humoral immunity. This study was designed to define the circulating antibodies specific to centenarians. RESULTS: We used a phage-displayed combinatorial peptide library to screen for peptides (YSATLRY and YSPTLFY) that preferentially react with ...

Stochastic resetting in backtrack recovery by RNA polymerases [PDF]
Transcription is a key process in gene expression, in which RNA polymerases produce a complementary RNA copy from a DNA template. RNA polymerization is frequently interrupted by backtracking, a process in which polymerases perform a random walk along the DNA template.

Structure and Function of a Mycobacterial NHEJ DNA Repair Polymerase [PDF]
Non homologous end-joining (NHEJ)-mediated repair of DNA double-strand breaks in prokaryotes requires Ku and a specific multidomain DNA ligase (LigD).

RNA-directed DNA methylation involves co-transcriptional small-RNA-guided slicing of polymerase V transcripts in Arabidopsis. [PDF]
Small RNAs regulate chromatin modifications such as DNA methylation and gene silencing across eukaryotic genomes. In plants, RNA-directed DNA methylation (RdDM) requires 24-nucleotide small interfering RNAs (siRNAs) that bind to ARGONAUTE 4 (AGO4) and ...

Inhibition of Ebola Virus by Anti-Ebola miRNAs in silico
Introduction: MicroRNAs (miRNAs) are small, noncoding RNA molecules that regulate transcriptional and posttranscriptional gene regulation of the organisms. miRNA provides immune defense when the body is faced with challenges intracellular agents.
