A Critical Guide to the PDB https://tess.elixir-europe.org/materials/a-critical-guide-to-the-pdb This Critical Guide in the Introduction to Bioinformatics series provides a brief outline of the Protein Data Bank – the PDB – the world’s primary repository of biological macromolecular structures. The rationale for creating the resource and the kinds of information it provides are discussed, and issues relating to its evolution and growth are explored. Specifically, this Guide introduces the principal features of the PDB, the nature (and quality) of its contents and how these may be interrogated. On reading this Guide, users will be able to: i) explain some of the ways in which knowledge of protein structures is useful; ii) identify the constituent databases of the wwPDB; iii) explain key features of the RCSB PDB in terms of its data distribution, growth and redundancy statistics; iv) search the PDB using simple and advanced keywords and full sequences, and analyse differences between them; and v) explain various structural quality criteria, and infer the quality of individual PDB entries.

A Critical Guide to the UniProtKB Flat-file Format https://tess.elixir-europe.org/materials/a-critical-guide-to-the-uniprotkb-flat-file-format This Critical Guide briefly presents the need for biological databases and for a standard format for storing and organising biological data. Web-based interfaces have made databases more user-friendly, but knowledge of the underlying file format offers a deeper understanding of how to navigate and mine the information they contain, so that humans and machines can get the most out of them. This Guide explores the file format that underpins one of today’s most popular protein sequence databases – UniProtKB. Specifically, this Guide introduces the concept of database ‘flat-files’, and examines features of the UniProtKB flat-file format. On reading this Guide, users will be able to: i) identify key fields within UniProtKB/Swiss-Prot and UniProtKB/TrEMBL flat-files; ii) explain what these fields mean, what information they contain and what the information is used for; iii) analyse the information in different fields and infer structural and functional features of a sequence; iv) examine and investigate the provenance of annotations; and v) compare annotations at different time-points and evaluate the likely impact of annotation changes.
