I have a basic question for people who have access to the cambridge database. I run Sybyl 6.0 at UTK, and several of the users here would like to know if there exists any enzymes related to cell signaling. If there are any people with access to enzyme structures of this type, please email me back. Mainly, I'm looking for sybyl mol2 files that are in the public domain. Thanks, Edward Wolpert wolpert \\at// neon.chem.utk.edu
