Crystal structure of the processivity clamp loader gamma (gamma) complex of E. coli DNA polymerase III.
D.Jeruzalmi, M.O'Donnell, J.Kuriyan.
 
  ABSTRACT  
 
The gamma complex, an AAA+ ATPase, is the bacterial homolog of eukaryotic replication factor C (RFC) that loads the sliding clamp (beta, homologous to PCNA) onto DNA. The 2.7/3.0 A crystal structure of gamma complex reveals a pentameric arrangement of subunits, with stoichiometry delta':gamma(3):delta. The C-terminal domains of the subunits form a circular collar that supports an asymmetric arrangement of the N-terminal ATP binding domains of the gamma motor and the structurally related domains of the delta' stator and the delta wrench. The structure suggests a mechanism by which the gamma complex switches between a closed state, in which the beta-interacting element of delta is hidden by delta', and an open form similar to the crystal structure, in which delta is free to bind to beta.

Figure 3.
Figure 3. γ:γ Interfacial Nucleotide Binding Sites Compared to the NSF Homolog p97(A) The nucleotide binding site of p97 (left) (Zhang et al., 2000) (PDB code 1E32) is compared to that of γ2 (at the γ1-γ2 interface, middle) and of γ3 (at the γ2-γ3 interface, right). For the γ structures, Domains I and II are colored, and Domain III is shown in gray. A schematic representation of the Domain I–II units is shown below the structures. ADP bound to p97 is shown at the active site of γ2 (middle) and γ3 (right) for reference. The arginine side chains of the Sensor 1 region are shown in dark blue at each interface.(B) The Sensor 1 region of γ1 is buried at the γ1-γ2 interface. On the left, the γ1-γ2 pair of subunits is shown, with the molecular surface of γ2 colored in gray, highlighted in red where γ1 contacts the γ2 surface. γ1 is shown as a green tube representing the backbone, with the Sensor 1 region colored magenta. γ2 is shown with the surface removed on the right
Figure 4.
Figure 4. The δ′ Stator Is Unlikely to Cause Closure of the Adjacent γ1 ATP Binding SiteOn the left, the γ1 (green) and γ2 (red) pair of subunits is shown, with Sensor 1 of γ1 (magenta) positioned near the ATP binding site of γ2 (indicated in gray). The first helix of Domain III of γ1, α10, is shown as a magenta tube to highlight the flexible linker connecting it to the last helix of Domain II. On the right, γ2 is shown again, in the same orientation as on the left (red). The γ1 subunit is replaced by δ′ (orange), which has been superimposed on γ1 using the C-terminal domain. Note that helix α10 in δ′ is extended at its N terminus relative to the structure seen in γ1, so that the connection to Domain II no longer appears to be flexible. The overall conformation of δ′ is more closed than that of γ1, so that the Sensor 1 region of δ′ is no longer located as close to the ATP binding site of γ2 as that of γ1

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
