Special Issue Information

Dear Colleagues,

During the process of DNA replication, DNA polymerases add mononucleotides into a growing primer using a DNA or RNA template to guide each incorporation event. While conceptually simple, this process is remarkably challenging due to the structural diversity in DNA and nucleotide substrates as well as in the number of DNA polymerases that are involved in the cellular replication of nuclear and mitochondrial DNA. In this Special Issue, we have asked international experts in this field to use their expertise to provide novel insights into the mechanism and structure of these important and enigmatic enzymes. The topics of this Special Issue include discussions on our current understanding of how high- and low-fidelity DNA polymerases replicate both normal and damaged DNA. Additional areas of interest focus on drug development, specifically toward generating potent and selective therapeutic agents against DNA polymerases involved in cancer and viral/bacterial infections. Finally, several articles will focus on current and emerging biotechnical methodologies including PCR and genomic sequencing. Collectively, this Special Issue will provide an outstanding collection of work highlighting the key principles in catalysis and fidelity of DNA polymerases, as well as how mutagenesis and pathological conditions can arise from defects in fidelity.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Molecules is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Title: Conformation-Specific Replication Block and Mutagenicity from Bulky DNA Lesions

Abstract: Bulky DNA adducts often exist in multiple conformations that are slowly interconverted to one another. Different conformations have shown to lead to different kinetic and binding capacities, presumably resulting in different mutational consequences. Studies on conformation-specific replication block are lacking, probably due to the complex dynamic nature of DNA replication. Recently, we investigated sequence effects of bulky DNA lesions generated from carcinogenic arylamines. We utilized a combination of surface plasmon resonance (SPR) and HPLC-based steady-state kinetics as well as replication bypass and mutagenicity assays to study the conformational differences in vitro and in cell.
