Mutagenesis alters the catalytic mechanism of the light-driven enzyme protochlorophyllide oxidoreductase.

The Journal of biological chemistry - 15 Jan 2010

Abstract excerpt

The light-activated enzyme protochlorophyllide oxidoreductase (POR) catalyzes an essential step in the synthesis of the most abundant pigment on Earth, chlorophyll. This unique reaction involves the sequential addition of a hydride and proton across the C17=C18 double bond of protochlorophyllide (Pchlide) by dynamically coupled quantum tunneling and is an important model system for studying the mechanism of...
