Abstract

The role of protein dynamics in promoting catalysis is hotly debated. Infrared data from both ultrafast flash photolysis and stopped-flow studies show that not only does there appear to be vibrational coupling between the cofactor and protein in B12-dependent ethanolamine ammonia lyase, but also that there are significant protein motions coupled to the reaction that follows substrate binding (see picture). © 2012 Wiley-VCH Verlag GmbH & Co.
