A random selection of article figures used in PDBsum

The 4 randomly selected references below show some of the article figures used in PDBsum. Each reference may relate to one or more PDBsum entries and may be one of the following types:
  • key reference - cited in the JRNL records in the corresponding PDB file,
  • secondary reference - listed in the REMARK records of the corresponding PDB file, or
  • added reference - either suggested by the author(s) or obtained from the journal in question (eg Acta Cryst D lists related PDB codes on its contents pages).
Note that only figures from the key and added references are displayed on the given entry's PDBsum page. Figures from the secondary references only appear on the entry's references page, which is reached via the "References" link on the left.

The figures used are either from Open Access publications or from journals for which we have obtained permission from the publishers to use their copyright material.

A maximum of 2 figures are selected from each reference. The selection is fully automatic, using an SVM trained to identify the most "interesting" figures in terms of structural or functional information content. However, in some cases, the figures may correspond to the article authors' preferred choice.

FIG. 1. Gel retardation experiments as to RBD1, RBD2, and RBD1-RBD2. As shown in A, 4 fmol of 32P-labeled r(GUUAGUUAGUUAGUU) (T4-3) was incubated with 0, 1.5, 4.4, 13, 40, and 120 pmol of either RBD1 (lanes 1-6) or RBD2 (lanes 7-12). The mixtures were run on polyacrylamide gel. As shown in B, 4 fmol of 32P-labeled T4-3 was incubated with 0, 0.008, 0.04, 0.2, 1, and 5 pmol of RBD1-RBD2 and run on polyacrylamide gel (lanes 1-6).

Figure 6. Refinement model of the ALR2 binding pocket at 0.95 Å resolution occupied by the pyridazinone inhibitor 6 shown in blue. For clarity, the specificity pocket is represented only in the open conformation. Amino acid residues are shown in orange, water molecules are indicated as red spheres. F[o] -F[c] density contoured at 3.5 s is shown in blue. It clearly depicts the positions of the inhibitor atoms.
Figure 7.
Figure 7. The F[o] -F[c] difference map next to residues in the catalytic center provides evidence for the protonation states of Tyr48, Lys77, His110, Trp111 and the pyridazinone moiety. Furthermore, a water molecule is indicated mediating a hydrogen bond network to His110 Nd2, Lys77 CO and the backbone NH groups of His46 and Val47. H bonds are shown as dotted green lines and the electron density corresponding to the hydrogen atoms is contoured in blue at 1.8 s. The inhibitor is shown in blue. The representation presents the binding pocket in two orientations: (a) the H bond interactions between the inhibitor and Tyr48 OH, His 110Ne2 and Trp111 Ne1; (b) clearly shows the threefold protonated Lys77 side-chain nitrogen atom involved in an H-bond network to Tyr48 OH, Asp43 Od2 and Cys44 CO.

Figure 2. Overview of the Structure of the Sec13-Nup145C Hetero-Octamer
(A) Ribbon representation of the Sec13-Nup145C hetero-octamer, showing Sec13 in yellow and orange and Nup145C in green and blue. A 90° rotated view is shown on the right. The three pseudo-two-fold axes (black ovals) that run through the hetero-octamer and the overall dimensions are indicated. The Sec13-Nup145C hetero-octamer forms a slightly bent rod.

Figure 5. Comparison of Ligand Binding Sites on LIR-1 D1D2 and KIR2DL1(A) Residues altered by site-directed mutagenesis are highlighted on a ribbon diagram of the LIR-1 D1D2 structure. Alteration of residues indicated in red resulted in changes in the affinity of LIR-1 D1D2 or LIR-2 D1D2 for UL18 (Table 2). Alteration of residues indicated in blue had no significant effect on the binding affinity.(B) Residues contributing to the KIR binding site for class I MHC molecules ([4, 42, 38, 43 and 6]) are highlighted on the structure of KIR2DL1 ( [16]).
