CC   -!- FUNCTION: DNA-dependent ATPase involved in processing of recombination
CC       intermediates, plays a role in repairing DNA breaks. Stimulates the
CC       branch migration of RecA-mediated strand transfer reactions, allowing
CC       the 3' invading strand to extend heteroduplex DNA faster. Binds ssDNA
CC       in the presence of ADP but not other nucleotides, has ATPase activity
CC       that is stimulated by ssDNA and various branched DNA structures, but
CC       inhibited by SSB. Does not have RecA's homology-searching function.
CC       {ECO:0000255|HAMAP-Rule:MF_01498}.
CC   -!- DOMAIN: Has a putative N-terminal zinc-finger, a middle region with
CC       homology to RecA with ATPase motifs including the RadA KNRFG motif,
CC       while the C-terminus is homologous to Lon protease. {ECO:0000255|HAMAP-
CC       Rule:MF_01498}.
CC   -!- SIMILARITY: Belongs to the RecA family. RadA subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_01498}.
