The reaction catalyzed by the light-driven enzyme protochlorophyllide oxidoreductase (POR) has been initiated with a 50-fs laser pulse. We show that the catalytic mechanism, involving proton and hydride transfers, proceeds with time constants of 3 ps and 400 ps. It is known that catalysis by POR involves thermally excited protein dynamics; our results show that these molecular motions occur on an ultrafast timescale.*Note: The version of this paper initially published online was incorrectly labeled as an 'Article'; the correct category should be 'Brief Communication'.
