RecA Is Required for the Assembly of RecN into DNA Repair Complexes on the Nucleoid.

Journal of bacteriology - 23 Sept 2021

McLean Emma K, Lenhart Justin S, Simmons Lyle A

Abstract excerpt

Homologous recombination requires the coordinated effort of several proteins to complete break resection, homologous pairing, and resolution of DNA crossover structures. RecN is a conserved bacterial protein important for double-strand break repair and is a member of the structural maintenance of chromosomes (SMC) protein family. Current models in Bacillus subtilis propose that RecN responds to double-stranded...
