Priming the Engine of DNA Synthesis [PDF]
In this issue of Structure, Rymer and colleagues present the first crystal structures of a bacterial DnaG primase with bound substrate NTPs and alarmone inhibitors. A thoughtful comparative structural analysis provides important insights into the chemical mechanism of primase.

DNA Synthesis Rescue involves resumption of DNA synthesis, polymeric linkage of deoxyribonucleotides by phosphate linkage, following arrest of DNA synthesis due to DNA damage. One rescue mechanism involves activation of proteins involved in DNA repair.

Synthesis and Properties of Isobicyclo‐DNA [PDF]
AbstractWe present the synthesis of the isobicyclo‐DNA building blocks with the nucleobases A, C, G and T, as well as biophysical and biological properties of oligonucleotides derived thereof. The synthesis of the sugar part was achieved in 5 steps starting from a known intermediate of the tricyclo‐DNA synthesis. Dodecamers containing single isobicyclo‐

Human cytomegalovirus protein pUL117 targets the mini-chromosome maintenance complex and suppresses cellular DNA synthesis. [PDF]
Modulation of host DNA synthesis is essential for many viruses to establish productive infections and contributes to viral diseases. Human cytomegalovirus (HCMV), a large DNA virus, blocks host DNA synthesis and deregulates cell cycle progression.

Nostoc edaphicum CCNP1411 from the Baltic Sea—A New Producer of Nostocyclopeptides
Nostocyclopeptides (Ncps) constitute a small class of nonribosomal peptides, exclusively produced by cyanobacteria of the genus Nostoc. The peptides inhibit the organic anion transporters, OATP1B3 and OATP1B1, and prevent the transport of the toxic ...

Terminator-free template-independent enzymatic DNA synthesis for digital information storage
DNA is an emerging medium for digital data and its adoption can be accelerated by synthesis processes specialized for storage applications. Here, we describe a de novo enzymatic synthesis strategy designed for data storage which harnesses the template ...

Large-scale de novo DNA synthesis: technologies and applications
For over 60 years, the synthetic production of new DNA sequences has helped researchers understand and engineer biology. Here we summarize methods and caveats for the de novo synthesis of DNA, with particular emphasis on recent technologies that allow ...

DNA Synthesis at a Fork in the Presence of DNA Helicases [PDF]
In a mixture of Escherichia coli DNA polymerase III holoenzyme, single‐strand‐binding protein, artificially forked λ bacteriophage DNA with primer annealed to the leading side of the fork, dNTPs and ATP, DNA synthesis is enhanced by helicaseII, less so by helicases I, III or rep protein of E. coli or T4 phage helicase. The effect of helicase II depends
