Properties of RecA441 protein reveal a possible role for RecF and SSB proteins in Escherichia coli.

Molecular & general genetics : MGG - 1 Jul 1991

Dri A M, Moreau P L

Abstract excerpt

We examined the possibility that the recA441 mutation, which partially suppresses the UV sensitivity of uvr recF mutant bacteria, exerts its effect by coding for an altered RecA protein that competes more efficiently than the RecA+ protein with SSB for ssDNA in vivo. Using an assay measuring recombination between UV-damaged lambda DNA and intact homologous DNA, we found that the introduction of the recA441...
