CC   -!- FUNCTION: Can catalyze the hydrolysis of ATP in the presence of single-
CC       stranded DNA, the ATP-dependent uptake of single-stranded DNA by duplex
CC       DNA, and the ATP-dependent hybridization of homologous single-stranded
CC       DNAs. It interacts with LexA causing its activation and leading to its
CC       autocatalytic cleavage. {ECO:0000255|HAMAP-Rule:MF_00268}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00268}.
CC   -!- SIMILARITY: Belongs to the RecA family. {ECO:0000255|HAMAP-
CC       Rule:MF_00268}.
