چکیده

(13)C-NMR experiments were performed on photo-excited fully and partially (13)C-labelled LOV2 domains of the blue-light receptor phototropin. In the present paper, we report on nuclear-spin polarized tryptophan resonances that are generated by light-induced intraprotein electron transfer to the FMN cofactor. The spectra are discussed with respect to earlier data obtained from (13)C-NMR experiments on unlabelled LOV2 domains that have been reconstituted with FMN (13)C isotopologues.

Photochemically induced dynamic nuclear polarization in a C450A mutant of the LOV2 domain of the Avena sativa blue-light receptor phototropin.

Phototropin is a blue-light receptor involved in the phototropic response of higher plants. The photoreceptor comprises a protein kinase domain and two structurally similar flavin-mononucleotide (FMN) binding domains designated LOV1 and LOV2. Blue-light irradiation of recombinant LOV2 domains induces the formation of a covalent adduct of the thiol group of a functional cysteine in the cofactor-...

Blue light-regulated molecular switch of Ser/Thr kinase in phototropin.

Phototropin is a blue light photoreceptor for tropic responses, relocation of chloroplasts, and stomata opening in plants. Phototropin has two chromophoric domains named light-oxygen-voltage-sensing (LOV) 1 and 2 in the N-terminal half, and a serine/threonine (Ser/Thr) protein kinase motif in the C-terminal half. Concerning the kinase activity of phototropin, only autophosphorylation has been d...

On the reaction mechanism of adduct formation in LOV domains of the plant blue-light receptor phototropin.

The blue-light sensitive photoreceptor, phototropin, is a flavoprotein which regulates the phototropism response of higher plants. The photoinduced triplet state and the photoreactivity of the flavin-mononucleotide (FMN) cofactor in two LOV domains of Avena sativa, Adiantum capillus-veneris, and Chlamydomonas reinhardtii phototropin have been studied by time-resolved electron paramagnetic reson...

Structure of a flavin-binding plant photoreceptor domain: insights into light-mediated signal transduction.

Phototropin, a major blue-light receptor for phototropism in seed plants, exhibits blue-light-dependent autophosphorylation and contains two light, oxygen, or voltage (LOV) domains and a serine/threonine kinase domain. The LOV domains share homology with the PER-ARNT-SIM (PAS) superfamily, a diverse group of sensor proteins. Each LOV domain noncovalently binds a single FMN molecule and exhibits...

Light-induced structural changes of the LOV2 domains in various phototropins revealed by FTIR spectroscopy

Phototropin (Phot), a blue-light photoreceptor in plants, consists of two FMN-binding domains (named LOV1 and LOV2) and a serine/threonine (Ser/Thr) kinase domain. We have investigated light-induced structural changes of LOV domains, which lead to the activation of the kinase domain, by means of light-induced difference FTIR spectroscopy. FTIR spectroscopy revealed that the reactive cysteine is...
