ABSTRACT
RecA is a DNA-dependent ATPase involved in DNA-strand repair. Most of the ATP hydrolysis that occurs in a RecA nucleoprotein filament is implicitly considered to be irrelevant in many current models for RecA-mediated DNA-strand exchange. However, preventing RecA from hydrolysing ATP alters its behavior, suggesting that ATP hydrolysis by RecA is more than incidental. This review explores recent results detailing the effects and rates of ATP hydrolysis by RecA, and models are proposed that permit us to account quantitatively for ATP consumption by this protein.
