Transcription-translation coupling: direct interactions of RNA polymerase with ribosomes and ribosomal subunits. [PDF]
, 2017 In prokaryotes, RNA polymerase and ribosomes can bind concurrently to the same RNA transcript, leading to the functional coupling of transcription and translation.

Microfluidic polymerase chain reaction [PDF]
, 2008 We implement microfluidic technology to miniaturize a thermal cycling system for amplifying DNA fragments. By using a microfluidic thermal heat exchanger to cool a Peltier junction, we have demonstrated rapid heating and cooling of small volumes of ...

Single-peptide DNA-dependent RNA polymerase homologous to multi-subunit RNA polymerase [PDF]
, 2017 Transcription in all living organisms is accomplished by multi-subunit RNA polymerases (msRNAPs). msRNAPs are highly conserved in evolution and invariably share a B400 kDa five-subunit catalytic core.

Reconstitution of recombination-associated DNA synthesis with human proteins. [PDF]
, 2013 The repair of DNA breaks by homologous recombination is a high-fidelity process, necessary for the maintenance of genome integrity. Thus, DNA synthesis associated with recombinational repair must be largely error-free.

Model of Transcriptional Activation by MarA in Escherichia coli [PDF]
, 2009 We have developed a mathematical model of transcriptional activation by MarA in Escherichia coli, and used the model to analyze measurements of MarA-dependent activity of the marRAB, sodA, and micF promoters in mar-rob- cells.

Dynamics of DNA replication loops reveal temporal control of lagging-strand synthesis [PDF]
, 2009 In all organisms, the protein machinery responsible for the replication of DNA, the replisome, is faced with a directionality problem. The antiparallel nature of duplex DNA permits the leading-strand polymerase to advance in a continuous fashion, but ...

SUMO Modification Stabilizes Enterovirus 71 Polymerase 3D To Facilitate Viral Replication. [PDF]
, 2016 Accumulating evidence suggests that viruses hijack cellular proteins to circumvent the host immune system. Ubiquitination and SUMOylation are extensively studied posttranslational modifications (PTMs) that play critical roles in diverse biological ...

Plasmid-based lacZalpha assay for DNA polymerase fidelity: application to archaeal family-B DNA polymerase [PDF]
, 2009 The preparation of a gapped pUC18 derivative, containing the lacZalpha reporter gene in the single-stranded region, is described. Gapping is achieved by flanking the lacZalpha gene with sites for two related nicking endonucleases, enabling the excision ...

Molecular dissection of the domain architecture and catalytic activities of human PrimPol [PDF]
, 2014 PrimPol is a primase–polymerase involved in nuclear and mitochondrial DNA replication in eukaryotic cells. Although PrimPol is predicted to possess an archaeo-eukaryotic primase and a UL52-like zinc finger domain, the role of these domains has not been ...

Cell, 1999 The appearance of these structures represents a historic advance in our understanding of one of molecular biology's most remarkable enzymes. Here we have suggested several possible structural bases for key steps in its function. Although speculative, they should serve as stimuli for future work.
