Dr. Kemp received his B.A. in Chemistry from the College of Wooster in 1959 and his Ph.D. in Biochemistry from Yale University in 1964. Following post-doctoral studies at the University of Washington, he was appointed assistant professor at the Medical College of Wisconsin, where from 1968 to 1973, he was an Established Investigator of The American Heart Association. In 1971, Dr. Kemp was a Fulbright Fellow to The Southern University of Chile. Dr. Kemp was appointed Professor in 1975 and moved to the Finch University of Health Sciences/The Chicago Medical School as chairman of Biochemistry in 1976, a position he held until 1989. Dr. Kemp has served on the research committee of the Leukemia Research Foundation and was a member of a National Institutes of Health Study Section.



Metabolic control mechanisms; structure/function studies of allosteric enzymes.

 

RESEARCH

Dr. Kemp's interest is in cellular regulatory mechanisms with particular emphasis on the structure and properties of allosteric enzymes. The laboratory focuses on phosphofructokinase, the key regulatory enzyme of carbohydrate metabolism in virtually all organisms. This enzyme has complex regulatory properties and displays tremendous regulatory diversity throughout the biosphere.

  • Allosteric properties of mammalian phosphofructokinase and the nature of allosteric binding sites are being studied by a combination of recombinant DNA and chemical techniques including site-directed mutagenesis, affinity modification methodology, protein sequence analysis, equilibrium binding studies, polymeric state analysis and kinetic studies.
  • The mechanism of catalysis is under investigation with particular emphasis on the PPi-dependent enzyme from parasitic protozoa.
