Julie A. Maupin-Furlow

Professor

Department of Microbiology and Cell Science University of Florida 
Ph.D. University of Florida, Microbiology and Cell Science

Post-doctoral work at the Department of Anaerobic Microbiology, Virginia Tech and The Department of Biochemistry and Molecular Biology at Penn State University

Teaching Interest

MCB4403  Prokaryotic Cell Structure and Function

MCB5408  Anaerobic Microbiology and Biotechnology

Description of Research

General area: regulation of cells by proteolytic enzymes and a specialization in proteasomes (multicatalytic nucleotide-dependent proteases) from the methanogenic and halophilic archaea.

Interests also include metabolic engineering of bacteria with emphasis on the structure-function of pyruvate decarboxylase for optimization of its activity in organisms growing at high temperature and low pH.  Her research employs biochemical, molecular, genomic, and structural biology techniques to investigate fundamental aspects of microbial metabolism and physiology.
