- solvent-accessible surface
Structural superposition
has its own article.
Domain definition
- http://pdomains.sdsc.edu offering an interface for comparing a number of different methods for automatic domain definition. For domain interfaces SCOPPI may be helpful.
- http://www.ebi.ac.uk/pdbe/docs/sifts/ a list of tab delimited files that contain all the information for each chain in the PDB. The information is also available per residue in XML format that contain additional annotation. These files are updated every week.
- A collection of links to structure-based domain parsers is at http://binf.gmu.edu/ttaylor/homepagelinks.html
- Domain boundaries are available through RCSB PDB RESTful web services described at: http://www.pdb.org/pdb/software/rest.do. For example, the URL http://www.pdb.org/pdb/rest/das/pdbchainfeatures/features?segment=1AJH.A returns an XML file with SCOP, CATH, DP, PDP, PFAM, InterPro domain boundaries, plus secondary structure information by DSSP, STRIDE, and the structure author.
- In the sequence tab for each PDB entry, (for example, http://www.pdb.org/pdb/explore/remediatedSequence.do?structureId=1AJH), the domain assignment from SCOP, DP, CATH etc. are given.
Functional annotation
- GOdot webserver for predicting function from structure (see http://dx.plos.org/10.1371%2Fjournal.pcbi.1000105)
- ProFunc Analysis of a protein's 3D structure to help identify its likely biochemical function
- Annotation PSI Stuctural Genomics knowledgebase
Docking
- ClusPro - easy to use web interface
- Rosetta can do much more than just docking, but is difficult to use
- 3D-dock - uses an algorithm that mainly looks at surface complimentarity between the two proteins
- Dave Ritchie's Hex program - it is blisteringly quick
- Haddock - recommended by Tassos
- AutoDock - Wiki at https://www.nbcr.net/pub/wiki/index.php?title=AutoDock
- DockBlaster - runs DOCK 3.5.54; there's a wiki
Other stuff
- pKa of protein - evaluated in: Crystallography Reviews, Volume 15, Issue 4 October 2009 , pages 231 - 259 An evaluation review of the prediction of protonation states in proteins versus crystallographic experiment Authors: Stuart J. Fisher; James Wilkinson; Richard H. Henchman; John R. Helliwell available at:- http://www.informaworld.com/smpp/content~db=all~content=a915050320~tab=content~order=page
- Programs for visualization (see also Model building)
- Links to Bioinformatics websites
- programs with chemistry knowledge, e.g. to build 3D-coordinates from 2D drawings
- modeling of glycosylation with GlyProt
- PDBeStatistics and some explanation of it
