Areas of interest: the nature and regulation of carbohydrate transport in micro-organisms
Our main research investigates:
- (1) the mechanisms by which carbohydrates (such as glucose and fructose) are transported across the cell membrane of E.coli and enter the metabolic routes of the organism, and
- (2) the manner in which these processes are regulated, This involves use of microbiological, biochemical and genetic procedures.
Current projects underway attempt to answer questions such as:
- what happens when two carbohydrates are presented to the cell at the same time - which is utilized in preference to the other and why?
- why do non-metabolizable analogs of glucose (such as methyl alpha-glucoside) inhibit growth on some substrates but not on others? And how do mutations that alter these phenotypes exert their effect?
- how do E.coli regulate gluconeogenesis?
- why does deletion of the gene specifying 1-phosphofructokinase (fruK) result in derepression of fructose uptake and how do nearby gene(s) reverse this effect without restoring FruK activity?
