In addition to facilitating the auto-catalytic cleavage of LexA repressor (as in the answer above), RecA in the form of a nucleoprotein filament facilitates cleavage of UmuD to UmuD', and as an ATP-bound monomer is a subunit of Pol V (UmuD'(2)C). All of these activities are a components of the SOS response.
