Guide to Understanding PDB Data
The constantly-growing PDB is a reflection of the research that is happening in laboratories across the world. This can make it both exciting and challenging to use the database in research and education.
Where are all the hydrogen atoms in this file? Should I care about the R-factor? Why are there 20 overlapped structures in my file? These questions and many others are explored in PDB-101's Guide to Understanding PDB Data. This resource was created to help users navigate through the contents of the archive without having a detailed background in structural biology. Topics cover biological assemblies, molecular graphics programs, R-value and R-free, and more.
