Saccharin has been part of the human diet for over 100 years, and there is a comprehensive body of evidence demonstrating that it can influence the gut microbiome, ultimately impacting human health. However, the precise mechanisms through which sacch... Read More about Saccharin disrupts bacterial cell envelope stability and interferes with DNA replication dynamics.

The human HELQ helicase and XRN2 exoribonuclease cooperate in R-loop resolution (2025)
Journal Article
Pan, J. M., Betts, H., Cubbon, A., Bolt, E. L., Soultanas, P., & He, L. (2025). The human HELQ helicase and XRN2 exoribonuclease cooperate in R-loop resolution. Open Biology, 15(2), https://doi.org/10.1098/rsob.240112

The human HELQ helicase is a superfamily 2, 3’-5’ helicase homologous to POLQ and RNA helicases of the Ski2-like subfamily. It is involved in diverse aspects of DNA repair and is an emerging prognosis biomarker and novel drug-target for cancer therap...

Human DDX49 is an emerging target in cancer progression and retroviral diseases through its essential roles in nucleolar RNA processing. Here, we identify nuclease activity of human DDX49, which requires active site aspartate residues within a conser...

POLD3 as Controller of Replicative DNA Repair (2024)
Journal Article
Alli, N., Lou-Hing, A., Bolt, E. L., & He, L. (2024). POLD3 as Controller of Replicative DNA Repair. International Journal of Molecular Sciences, 25(22), Article 12417. https://doi.org/10.3390/ijms252212417

Multiple modes of DNA repair need DNA synthesis by DNA polymerase enzymes. The eukaryotic B-family DNA polymerase complexes delta (Polδ) and zeta (Polζ) help to repair DNA strand breaks when primed by homologous recombination or single-strand DNA ann...

Escherichia coli DNA repair helicase Lhr is also a uracil-DNA glycosylase (2023)
Journal Article
Buckley, R. J., Lou-Hing, A., Hanson, K. M., Ahmed, N. R., Cooper, C. D., & Bolt, E. L. (2023). Escherichia coli DNA repair helicase Lhr is also a uracil-DNA glycosylase. Molecular Microbiology, 120(2), 298-306. https://doi.org/10.1111/mmi.15123

DNA glycosylases protect genetic fidelity during DNA replication by removing potentially mutagenic chemically damaged DNA bases. Bacterial Lhr proteins are well-characterized DNA repair helicases that are fused to additional 600–700 amino acids of un...

Archaeal Hel308 suppresses recombination through a catalytic switch that controls DNA annealing (2023)
Journal Article
Lever, R., Simmons, E., Gamble-Milner, R., Buckley, R., Harrison, C., Parkes, A., Mitchell, L., Gausden, J., Škulj, S., Bertoša, B., Bolt, E. L., & Allers, T. (2023). Archaeal Hel308 suppresses recombination through a catalytic switch that controls DNA annealing. Nucleic Acids Research, 51(16), 8563-8574. https://doi.org/10.1093/nar/gkad572

Hel308 helicases promote genome stability in archaea and are conserved in metazoans, where they are known as HELQ. Their helicase mechanism is well characterised, but it is unclear how they specifically contribute to genome stability in archaea. We s...
