摘要：

Cheap and safe: The catalytic efficiency of a light-dependent photoenzyme (NADPH: protochlorophyllide oxidoreductase) is investigated as a function of the excitation wavelength (see picture). It becomes evident that red photons are more efficiently utilized in enzyme catalysis than blue photons. This shows an adaptation of the enzyme activity to the natural light conditions. © 2012 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.
