The MgsA protein possesses DNA-dependent ATPase and ssDNA annealing activities [1]. MgsA contributes to the recovery of stalled replication forks and therefore prevents genomic instability caused by aberrant DNA replication [1]. Additionally, MgsA may play a role in chromosomal segregation [1]. This is consistent with a report that MgsA co-localises with the replisome and affects chromosome segregation [1]. This domain represents the C terminal region of MgsA.	Domain
