A mutant Pfu DNA polymerase designed for advanced uracil-excision DNA engineering
BMC Biotechnology, 2010 Background The combined use of restriction enzymes with PCR has revolutionized molecular cloning, but is inherently restricted by the content of the manipulated DNA sequences.

Mutations that Separate the Functions of the Proofreading Subunit of the Escherichia coli Replicase
, 2015 The dnaQ gene of Escherichia coli encodes the Ɛ subunit of DNA polymerase III, which provides the 3\u27 - 5\u27 exonuclease proofreading activity of the replicative polymerase.

Interdependent interactions between TFIIB, TATA binding protein, and DNA. [PDF]
, 2002 Temperature-sensitive mutants of TFIIB that are defective for essential interactions were isolated. One mutation (G204D) results in disruption of a protein-protein contact between TFIIB and TATA binding protein (TBP), while the other (K272I) disrupts an ...

Isolation and characterization of monoclonal antibodies directed against two subunits of rabbit poxvirus-associated, DNA-directed RNA polymerase [PDF]
Journal of Virology, 1985 A library of monoclonal antibodies directed against individual proteins of the rabbit poxvirus (RPV) virion within a complex immunogenic mixture has been generated through the use of in vivo and in vitro immunization regimens. The relative efficacies of the two procedures were compared.

Circulating tumor cells: advancing personalized therapy in small cell lung cancer patients
Molecular Oncology, EarlyView.Small cell lung cancer (SCLC) is an aggressive form of lung cancer that spreads rapidly to secondary sites such as the brain and liver. Cancer cells circulating in the blood, “circulating tumor cells” (CTCs), have demonstrated prognostic value in SCLC, and evaluating biomarkers on CTCs could guide treatment decisions such as for PARP inhibitors ...

A design proposal of the reverse DNA polymerase (3'-5' direction) [PDF]
arXiv, 2013 DNA Polymerase is an enzyme that participates in the process of DNA replication. In general, forward DNA polymerase moves along the template strand in a 3'-5' direction, and the daughter strand is formed in a 5'-3' direction. This paper theoretically analyzes the mechanism of forward DNA polymerase, and gives the design proposal of a new reverse DNA ...

Metal A and metal B sites of nuclear RNA polymerases Pol IV and Pol V are required for siRNA-dependent DNA methylation and gene silencing. [PDF]
PLoS ONE, 2009 Plants are unique among eukaryotes in having five multi-subunit nuclear RNA polymerases: the ubiquitous RNA polymerases I, II and III plus two plant-specific activities, nuclear RNA polymerases IV and V (previously known as Polymerases IVa and IVb).

alpha-helix E of Spo0A is required for sigma(A)- but not for sigma(H)-dependent promoter activation in Bacillus subtilis [PDF]
, 2004 At the onset of endospore formation in Bacillus subtilis, the DNA binding protein Spo0A activates transcription from two types of promoters. The first type includes the spoIIG and spoIIE promoters, which are used by sigma(A)-RNA polymerase, whereas the ...

RanBP2-Mediated SUMOylation Promotes Human DNA Polymerase Lambda Nuclear Localization and DNA Repair [PDF]
, 2020 Cellular DNA is under constant attack by a wide variety of agents, both endogenous and exogenous. To counteract DNA damage, human cells have a large collection of DNA repair factors. Among them, DNA polymerase lambda (Polλ) stands out for its versatility,
