I would recommend to use the new PROSITE/Profile server at


Simple motifs like ATP-binding sites, Zn-fingers, EF-hands etc. can
be searched with one of the PROSITE/patterns servers like

  http://ulrec3.unil.ch/software/PSTSCAN_form.html     or

More divergent motifs like SH2, SH3, C2, kinases etc. can be searched
with the Profile part of PROSITE


PEST regions can be searched at 

and Coiled-Coil regions at


A collection of these and related servers for protein analysis can be
found on my link page


I hope these suggestions are helpful.
