CRYSTAL STRUCTURE OF THE DELTA PRIME SUBUNIT OF THE CLAMP-LOADER COMPLEX OF ESCHERICHIA COLI DNA POLYMERASE III

Overview

The crystal structure of the delta' subunit of the clamp-loader complex of, E. coli DNA polymerase III has been determined. Three consecutive domains, in the structure are arranged in a C-shaped architecture. The N-terminal, domain contains a nonfunctional nucleotide binding site. The catalytic, component of the clamp-loader complex is the gamma subunit, which is, homologous to delta'. A sequence-structure alignment suggests that, nucleotides bind to gamma at an interdomain interface within the inner, surface of the "C." The alignment is extended to other clamp-loader, complexes and to the RuvB family of DNA helicases, and suggests that each, of these is assembled from C-shaped components that can open and close the, jaws of the "C" in response to ATP binding and hydrolysis.
