Research interestsDr. Ciarán Fagan seeks to improve the stability of enzymes.
Enzymes are ideal “green” catalysts: they can enable newer processes that are less hazardous and less costly than traditional methods, while producing less waste.
Enzymes’ many industrial applications range from detergents to the food and (bio)pharma industries. Unfortunately, enzymes may become unstable and lose their catalytic abilities under the demands of process conditions, or upon prolonged use or extended storage.
Dr. Fagan uses two main strategies to increase the stability of enzymes, namely protein engineering and chemical modification. He has prepared enzymes that are more tolerant of heat, organic solvents or oxidizing conditions, or that give improved biosensor performance.
Although he has worked on numerous enzymes, his special focus is on plant peroxidases (which are used for a variety of purposes). These, together with a “resurrected” ancient plant peroxidase, an evolutionary precursor of the modern-day enzymes, provide opportunities for postgraduate research.
