Validation reports contain an assessment of the quality of a structure and highlight specific concerns by considering the coordinates of the model, the experimental data and the fit between the two.
Easily interpretable summary information that compares the quality of a model with that of other models in the archive will help users of PDB data to critically assess archived entries and to select the most appropriate structural models for their needs.
Access Pose View images in the Ligand Chemical Component section on an entry's Structure Summary. Provides a graphical summary of a full-length protein sequence from  Uni Prot and how it corresponds to PDB entries.
It also loads annotations from external databases (such as Pfam) and homology models information from the Protein Model Portal.
Annotations visualizing predicted regions of protein disorder and hydrophobic regions are displayed. Examples:  Breast Cancer Type 1 Protein,  Gag-Pol Polyprotein, and  Hemoglobin Alpha (shown image).
This feature is available from the Molecular Description widget on Structure Summary pages and by entering a Uni Prot ID below.
Explore metabolic pathways maps that identify pathway components with PDB structures and homology models.Maps can be accessed from the Protein View (see example  P29401), and the main  Pathway View page.Pose View images are 2D diagrams that show a ligand and interacting residues.Global percentile ranks (black vertical boxes) are calculated with respect to all X-ray structures available prior to 2011.Resolution-specific percentile ranks (white vertical boxes) are calculated considering entries with similar resolution.
