Smart polymers provide light-activated switch to turn enzymes on and off

Researchers have applied studies in how proteins bind with different molecules to create a molecular switch that enables them to turn an enzyme on and off. The innovation holds promise for a wide range of laboratory processes, including highly targeted drug therapies. The study, published this week in the Proceedings of the National Academy of Science, describes a reversible switch for the enzyme endoglucanase in which light is the trigger for turning the switch on and off.
