Solution study of the Escherichia coli DNA polymerase III clamp loader reveals the location of the dynamic ψχ heterodimer

چکیده
Several X-ray crystal structures of the E. coli core clamp loader containing the five core (δ', δ, and three truncated γ) subunits have been determined, but they lack the ψ and χ subunits. We report the first solution structure of the complete seven-subunit clamp loader complex using small angle X-ray scattering. This structure not only provides information about the location of the χ and ψ subunits but also provides a model of the dynamic nature of the clamp loader complex.

Interplay of clamp loader subunits in opening the beta sliding clamp of Escherichia coli DNA polymerase III holoenzyme.
The Escherichia coli beta dimer is a ring-shaped protein that encircles DNA and acts as a sliding clamp to tether the replicase, DNA polymerase III holoenzyme, to DNA. The gamma complex (gammadeltadelta'chipsi) clamp loader couples ATP to the opening and closing of beta in assembly of the ring onto DNA. These proteins are functionally and structurally conserved in all cells. The eukaryotic equi...
متن کاملCrystal structure of the chi:psi sub-assembly of the Escherichia coli DNA polymerase clamp-loader complex.
The chi (chi) and psi (psi) subunits of Escherichia coli DNA polymerase III form a heterodimer that is associated with the ATP-dependent clamp-loader machinery. In E. coli, the chi:psi heterodimer serves as a bridge between the clamp-loader complex and the single-stranded DNA-binding protein. We determined the crystal structure of the chi:psi heterodimer at 2.1 A resolution. Although neither ch...
متن کاملClamp loader structure predicts the architecture of DNA polymerase III holoenzyme and RFC
Recent determinations of the crystal structure of the Escherichia coli gamma complex and delta-beta assembly have shed light on the bacterial clamp loading reaction. In this review, we discuss the structures of delta-beta and the gamma(3)deltadelta' complex and its mechanism of action as a clamp loader of the E. coli beta sliding clamp. We also expand upon the implications of the structural fin...
متن کاملContributions of the individual hydrophobic clefts of the Escherichia coli β sliding clamp to clamp loading, DNA replication and clamp recycling
The homodimeric Escherichia coli beta sliding clamp contains two hydrophobic clefts with which proteins involved in DNA replication, repair and damage tolerance interact. Deletion of the C-terminal five residues of beta (beta(C)) disrupted both clefts, severely impairing interactions of the clamp with the DnaX clamp loader, as well as the replicative DNA polymerase, Pol III. In order to determi...
متن کاملReplisome architecture and dynamics in Escherichia coli.
The field of DNA replication was launched upon discovery of the first DNA polymerase by Kornberg and Lehman (1, 2). DNA polymerase I displayed the novel and highly exciting property of template-directed enzymatic action, and like a split personality, DNApolymerase I could also degradeDNA, from either direction. Escherichia coli is now known to contain five different DNA polymerases. The chromos...
