Bacteriochlorophyll a biosynthesis requires the stereo- and regiospecific two electron reduction of the C7-C8 double bond of chlorophyllide a by the nitrogenase-like multisubunit metalloenzyme, chlorophyllide a oxidoreductase (COR). ATP-dependent COR

The primary excited state processes of phytochrome, the plant chromoprotein responsible for most photomorphogenetic responses, are investigated by picosecond intensity-dependent transmission measurements. At sufficient high excitation intensity (star

Free porphyrins and their magnesium complexes, including chlorophylls, are potent photo-sensitizers. Plants usually accumulate these compounds bound to proteins together with protective compounds like carotenoids. Besides their protective role, carot

Phototropins are a family of plant photoreceptors mediating blue light responses such as phototropism, leaf expansion, chloroplast relocation, and stomatal opening. Characteristic for phototropins are two LOV domains which, when expressed in heterolo

The pigments of etiolated leaves of barley (Hordeum vulgare L.) were analysed during dark periods after flash illumination, and the results were compared with in vivo spectroscopy of the leaves. Pretreatment of the leaves with kinetin slightly stimul

Phototropin (phot) is a UV/blue- light receptor mediating phototropic reactions of plants as a response to unilateral irradiation. Using an antiserum directed against the N-terminal part of Arabidopsis phot1, we show here cross-reaction with phototro

The temporal evolution of the initially excited singlet state of flavine mononucleotide, which is the cofactor in the LOV2 domain of the blue photoreceptor phototropin, has been studied in picosecond time-resolved fluorescence and femtosecond time-re

Using circular dichroism (CD) spectroscopy, the stereochemistry at C-13(2) of members of the chlorophyll (Chl) c family, namely Chls c(1), c(2), c(3) and [8-vinyl]-protochlorophyllide a (Pchlide a) was determined. By comparison with spectra of known
