The RecD2 helicase balances RecA activities [PDF]

open access: yesNucleic Acids Research, 2022
AbstractDNA helicases of the RecD2 family are ubiquitous. Bacillus subtilis RecD2 in association with the single-stranded binding protein SsbA may contribute to replication fork progression, but its detailed action remains unknown. In this work, we explore the role of RecD2 during DNA replication and its interaction with the RecA recombinase.
