This dataset formed the basis of the work described in (Yao and Grant 2013) and we refer the motivated reader to this publication and references therein for extensive background information.

The main purpose of including this data (which may be generated by the user by following the extended examples documented within the various Bio3D functions) is to allow users to more quickly appreciate the capabilities of functions that would otherwise require extensive data downloads before execution.įor a number of the examples in the current vignette we will utilize the included transducin dataset that contains over 50 publicly available structures. various operations of PDB structures, analysis of MD trajectories and normal mode analysis can be found in corresponding vignettes.īefore delving into more advanced analysis lets examine how we can read multiple PDB structures from the RCSB PDB for a particular protein and perform some basic analysis:Įxploring example data for the transducin heterotrimeric G ProteinĪ number of example datasets are included with the Bio3D core package. More comprehensive demonstrations for special tasks, e.g. We will demonstrate some of these utilities in the following sections. even for the same protein as we will see below) and it is these differences that are frequently of most interest.įor this reason Bio3D contains extensive utilities to enable the reading and writing of sequence and structure data, sequence and structure alignment, performing homologous protein searches, structure annotation, atom selection, re-orientation, superposition, rigid core identification, clustering, torsion analysis, distance matrix analysis, structure and sequence conservation analysis, normal mode analysis across related structures, and principal component analysis of structural ensembles. The challenge of working with these structures is that they are usually different in their composition (i.e. contain differing number of atoms, sequences, chains, ligands, structures, conformations etc. The Bio3D package was designed to specifically facilitate the analysis of multiple structures from both experiment and simulation.
