Useful Links :
You may find the following links helpful in your studies this semester. The standard Internet disclaimer applies though: Just because you see it on your computer screen doesn't means it is correct! When in doubt, do more research.
Structural Databases:
Protein Data Bank (PDB)
Molecular Modeling Database
Most Representative NMR structure in an Ensemble
Protein Quaternary Structure at EBI
Structural Classification Algorithms
CATH: CATH is a hierarchical classification of protein domain structures, which clusters proteins at four major levels: Class (C), Architecture (A), Topology (T) and Homologous superfamily (H).
CE: Protein structural alignment using combinatorial extension. The reference for the algorithm can be found here.
Dali/FSSP: Protein structural comparisons using the Dali algorithm. References for the technique can be found here (Nucleic Acids Research, 1997, Vol. 25, No. 1) and here (Bioinformatics Vol. 24 No. 23 2008, pages 2780–2781).
SCOP: Structural Classification of Proteins. The reference for the SCOP database is here.
VAST: Vector Alignment Search Tool at NCBI. A description of the tool is found on the website.
