<Dear Collegues,
<     I am wondering whether there is any protein data bank available
<which contains information on molecular weight, properties ect. rather
<than mere sequence. E. g. one would like to look for a protein with Mr.
<75 kD which has ATP binding activity or one looks for information on
<all helicases etc. Please send information concerning either the data
<bank itself or people who would be able to provide further help.
<                                  yours: Dieter Blaas


The SWISS-PROT protein data bank contains all these informations.

The molecular weight data is on the "SQ" line-type, the info on properties
(function) of the sequence are on the "CC" and "KW" lines. To show you what
I mean I include an example entry that fit with your example query: an
helicase, ATP-binding of around 75 Kd.
