This information and search capability are already available.  The ATLAS
program distributed on the CD-ROM with the PIR-International Protein Sequence
Data Base provides easily usable capabilities for searching protein sequences
by estimated molecular weight ranges in conjunction with other search
strategies.  The PIR Network Request Server can search for protein sequences
by estimated chain length ranges.  For more information, request HELP from
FILESERV at NBRF.Georgetown.EDU.
