The nucleotide binding domains of these polypeptides are highly conserved, but this similarity has failed to help us understand the biological role of the ATPase activity of the MutL proteins in mismatch repair. hMutLalpha is a heterodimer of the human MutL homologues hMLH1 and hPMS2, and we decided to exploit its asymmetry to study this function. We now show that although the two subunits contribute differently to the ATPase activity of the heterodimer, hMutLalpha variants in which one subunit was able to bind but not hydrolyze ATP displayed similarly reduced mismatch repair activities in vitro. In contrast, variants in which either subunit was unable to bind the nucleotide were inactive. Mutation of the catalytic sites of both subunits abolished repair without altering the ability of these peptides to interact with one another. Since the binding of the nucleotide in hMutLalpha was not required for the formation of ternary complexes with the mismatch recognition factor hMutSalpha bound to a heteroduplex substrate, we propose that the ATPase activity of hMutLalpha is required downstream from this process."xsd:string |
