Ultrafast enzymatic reaction dynamics in protochlorophyllide oxidoreductase (vol 10, pg 491, 2003)

Research output: Contribution to JournalArticleAcademicpeer-review

Abstract

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.
