Publication Abstract from PubMed
MutL and its homologs are essential for DNA mismatch repair. Mutations in genes encoding human homologs of MutL cause multiorgan cancer susceptibility. We have determined the crystal structure of a 40 kDa N-terminal fragment of E. coli MutL that retains all of the conserved residues in the MutL family. The structure of MutL is homologous to that of an ATPase-containing fragment of DNA gyrase. We have demonstrated that MutL binds and hydrolyzes ATP to ADP and Pi. Mutations in the MutL family that cause deficiencies in DNA mismatch repair and a predisposition to cancer mainly occur in the putative ATP-binding site. We provide evidence that the flexible, yet conserved, loops surrounding this ATP-binding site undergo conformational changes upon ATP hydrolysis thereby modulating interactions between MutL and other components of the repair machinery.
