CRYSTAL STRUCTURE OF THE DELTA PRIME SUBUNIT OF THE CLAMP-LOADER COMPLEX OF ESCHERICHIA COLI DNA POLYMERASE IIICRYSTAL STRUCTURE OF THE DELTA PRIME SUBUNIT OF THE CLAMP-LOADER COMPLEX OF ESCHERICHIA COLI DNA POLYMERASE III
Structural highlights
Function[HOLB_ECOLI] DNA polymerase III is a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria. This DNA polymerase also exhibits 3' to 5' exonuclease activity. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe 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.
