[[https://www.uniprot.org/uniprot/RECA_ECOLI RECA_ECOLI]] Can catalyze the hydrolysis of ATP in the presence of single-stranded DNA, the ATP-dependent uptake of single-stranded DNA by duplex DNA, and the ATP-dependent hybridization of homologous single-stranded DNAs. It interacts with LexA causing its activation and leading to its autocatalytic cleavage.[HAMAP-Rule:MF_00268]

== Publication Abstract from PubMed ==
The RecA protein forms a hexameric ring that is similar to the core of the F1-ATPase. Several lines of evidence suggest that this hexamer may be a structural homologue of ring helicases.
The RecA hexamer is a structural homologue of ring helicases.,Yu X, Egelman EH Nat Struct Biol. 1997 Feb;4(2):101-4. PMID:9033586<ref>PMID:9033586</ref>
