protein compendium?

[Kathryn Weiss]

I'm looking for some sort of compendium or encyclopedia of protein amino 
acid compositions, something that will list the amino acid composition.  
Does anyone know of a reference text or a database that will provide this 
information?  I am looking at some proteins isolated from plants, and would 
like to compare their composition with other proteins; I also would like 
to construct model systems with commercially available proteins with 
similar amino acid compositions.

Thanks,
