Then you have been sadly misinformed....

Swiss-Prot has links to ECO2DBASE, the E.coli 2D gel database from
F.Neidhardt. The 2D gel database itself is available by ftp from

         ncbi.nlm.nih.gov in directory repository/ECO2DBASE

and is also indexed on the SRS server (and cross-referenced to Swiss-Prot) at


where you will find it under "genome libraries" with the name EC2D.

We changed the database format slightly from the original distribution
(moved the column headings to be row headings so we get a neat flat file
format for an entry).

And yes, it does have MWt and pI, both calculated from sequence and
estimated from the gel.

For Swiss-Prot 31, and ECO2DBASE 6, we have 347 spots, linked to 297
Swiss-Prot entries.
