Unknown STructure ...

[karthik3k]

I want a list of Proteins of Unknown structure....
Where shall i find it ???

[Monique]

Don't most proteins have an unknown 3D (tertiary or quarternairy) structure? Or are you talking about the aminoacid (primary) structure?

The online repository for protein sequences is the ExPASy Molecular Biology Server (http://au.expasy.org/). The online repository for 3-D protein structures (determined by x-ray crystallography, NMR, etc.) is the Protein Data Bank (http://www.rcsb.org) .

Insofar as I know, there is no convenient listing of proteins without an experimentally determined 3-D structure. Your best bet is to find a protein in the ExPASy files and then check the PDB to see if there is a structure available. Trust me, a little bit of hard work never killed anyone. :)

You may also want to take a look at the Metalloprotein Database (http://metallo.scripps.edu/) at Scripps if you're interested in that sort of thing.
