Sue Aitken is a professor in the Department of Biology at Carleton University, specializing in enzymology and sulfur amino acid metabolism. Her research focuses on the mechanisms regulating enzymes involved in sulfur amino acid regulation in plants, humans, and microorganisms. Aitken employs various molecular biology techniques, including PCR, enzyme kinetics, and biophysical spectroscopy, to explore the biosynthesis of methionine in legumes, which are known to be deficient in this essential amino acid. Her work aims to develop new legume varieties with increased methionine levels, benefiting protein sources for human consumption. Additionally, Aitken investigates phytoremediation, an environmentally friendly approach to soil decontamination using hyperaccumulator plants to extract heavy metal contaminants. Her research extends to medical applications of methionine metabolism, particularly the risks associated with elevated homocysteine levels and heart disease. Aitken's contributions also encompass enzyme engineering for biotechnological applications, focusing on catalysis involving amino acids and requiring co-factors like pyridoxal phosphate.
