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?

Current research suggests a certain type of tiny fungus may play a very large role in the global cycling of carbon. Professor Finzi, who took part in the research, asserts that the work is not only relevant to climate models and predictions of future atmospheric greenhouse gas levels, but also challenges the core foundation in modern biogeochemistry that climate exerts major control over soil carbon pools.Read more.
