Dr. Jeffrey Hughes
Professor, Microbiology and Virology
LTSC329
217-424-6270
JHughes@millikin.edu
Dr. Hughes is a molecular biologist who studies metabolism of the nucleotide S-adenosyl-L-methionine (fondly known as “SAM”), primarily in the bacterium Escherichia coli. This important molecule is found in all cells and is involved in fruit ripening (plants), cell differentiation and cancer (animals), and a variety of activities in bacteria that include gene regulation, cell division, polyamine biosynthesis, methylation of many compounds including DNA, RNA, lipids and proteins. We are especially interested in cell division and an enzyme a virus of E. coli uses to cleave SAM as an essential first step in infecting the cell. Over 50 students have participated in these studies, most then heading to graduate and medical schools.
