Abstract
A method for regulating enzyme activity, which entails contacting one or more enzymes with a gas containing one or more noble gases or mixtures thereof. The activity of an enzyme on a substrate can be improved by contacting the enzyme with a noble gas under specific temperatures and pressures. The preferred noble gases are krypton, neon, xenon, argon or mixtures of these gases. The enzymes whose activity can be improved are hydrolases, lyases, isomerases and ligases.
