Project Description: Isoprene monooxygenase: A missing link in the global isoprene cycle

Isoprene is a highly abundant volatile compound with important climatic effects. Isoprene is emitted in similar quantities to methane (approximately 600 million tonnes per year), however it is markedly less studied. The first step in isoprene degradation is believed to be catalysed by a soluble diiron monooxygenase (SDIMO) called isoprene monooxygenase. SDIMOs are a group on enzymes including the extensively characterised soluble methane monooxygenase (sMMO), and many of them are of interest in bioremediation and biotechnology because of their classically diverse substrate ranges.

The aim of the project is to purify and characterise isoprene monooxygenase to develop a greater understanding of the mechanisms behind isoprene degradation and expand understanding of the SDIMO enzymes.
