==RECA HEXAMER MODEL, ELECTRON MICROSCOPY==

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.

[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]
