Beyond the Lesion: Back to High Fidelity DNA Synthesis
Frontiers in Molecular Biosciences, 2022 High fidelity (HiFi) DNA polymerases (Pols) perform the bulk of DNA synthesis required to duplicate genomes in all forms of life. Their structural features, enzymatic mechanisms, and inherent properties are well-described over several decades of research.

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 ...

LigD: A Structural Guide to the Multi-Tool of Bacterial Non-Homologous End Joining
Frontiers in Molecular Biosciences, 2021 DNA double-strand breaks are the most lethal form of damage for living organisms. The non-homologous end joining (NHEJ) pathway can repair these breaks without the use of a DNA template, making it a critical repair mechanism when DNA is not replicating ...

Social context prevents heat hormetic effects against mutagens during fish development
FEBS Letters, EarlyView.This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...

Directed evolution of novel polymerase activities: Mutation of a DNA polymerase into an efficient RNA polymerase [PDF]
Proceedings of the National Academy of Sciences, 2002 The creation of novel enzymatic function is of great interest, but remains a challenge because of the large sequence space of proteins. We have developed an activity-based selection method to evolve DNA polymerases with RNA polymerase activity.
