1ZE8 - PubMed Abstract: 
Structure for the adduct of carbonic anhydrase II with 1-N-(4-sulfamoylphenyl-ethyl)-2,4,6-trimethylpyridinium perchlorate, a membrane-impermeant antitumor sulfonamide, is reported. The phenylethyl moiety fills the active site, making van der Waals interactions with side chains of Gln192, Val121, Phe131, Leu198, Thr200 ...
