protein lengths

[Naomi Siew <nomsiew "at@at" cs.bgu.ac.il>]

Hi,
 I would like to rephrase my question:
 I am looking for a list of protein families, by function (e.g. GPCRs,
 ribozomes, immunoglobulins, Ser proteases, etc.), and their lengths.
 e.g. GPCRs - average length xxx residues (or: length range: xxx-yyy
 residues), etc.
 I am most interested to know which are the longest proteins.
 Those functional databases that I searched give a general length
 distribution for each organism.
 Perhaps I missed those that have a general length distribution, by
 function, for all the organisms sequenced thus far.
 Thanks,
 Naomi
