The Speaker: Dr. Sidney Katz received his A.B. in natural sciences from Rutgers University. He earned a Ph.D. in analytical chemistry from the University of Pennsylvania.  He did postdoctoral work at Rutgers, University of California at Irvine and at the Philadelphia College of Pharmacy and Science. He has been a Visiting Professor at numerous universities including the Reading University in England, the Debreceni Egyeten in Hungary, the University of Sindh in Pakistan and the University of Fort hare in South Africa. He has been at Rutgers University since 1960. His long publication record includes reviewed articles in Analytical Chemistry, Analytical Chimica and many other journals. He has also published books and book chapters on analytical topics. He has been awarded research funding from NIH, NSF, BUSCH, WPF and others. Dr. Katz was a NSF/AEC Fellow, a NATO Senior Fellow. He has also for many years held USIS Lectureships. In 1986, he held a Fulbright Lectureship. His research program has been focused on the role and fate of trace elements in environmental and biological systems as well as radiochemistry.

Abstract: The preparation and properties of a bacterial phosphatase that safely and efficiently detoxifies some fluoro derivatives of phosphate ester toxicants such as pesticides and nerve agents will be described. A phosphatase extracted from a special strain of Alteromonas was found to hydrolyze O,O-diisopropyl methyl phosphono-fluoridate, O-isopropyl methyl phosphonofluoridate, O-picacolyl phosphone diamino fluoridate, cyclohexly methyl phosphonofluoridate and N,N'-diisopropyl phosphone diamino fluoridate to the corresponding esters of phosphoric acid. The purified enzyme migrated as a 55 kD protein in SDS-PAGE. Optimal O,O-diisopropyl phosphono- fluoridate hydrolysis occurred at pH 8.0-8.4 and 40-45o. Hydrolysis of O,O-diisopropyl  phosphonofluoridate was stimulated by Ca+2, Co+2,  Mn+2 and Zn+2. The enzyme has potential application to the bio-catalytic detoxification of waste fluorophosphate toxicants.
