Metabolic stress occurs at disease onset and causes altered flavoprotein redox activity that increases flavoprotein autofluorescence (FA).
Electron transfer flavoprotein (ETF) from pig liver mitochondria has been purified to homogeneity by a three-step procedure with approx. 10-fold higher yields than previously reported. The purified ETF exhibits an absorption coefficient for the bound FAD of 13.5 mM-1.cm-1 at 436 nm and an isoelectric point of 6.75. Gel filtration, sodium dodecyl sulphate gel electrophoresis and flavin analysis indicate that pig liver ETF is a dimer, composed of non-identical subunits (Mr 38 000 and 32 000) with only one FAD/dimer. Anaerobic reduction by dithionite produces anionic flavin semiquinone as a stable intermediate and establishes the flavin to be the only redox-active chromophore in ETF. ...

AU - Li, Tanping. AU - Wang, Lijuan. AU - Zhong, Dongping. PY - 2010/9/15. Y1 - 2010/9/15. N2 - Flavoproteins are unique redox coenzymes, and the dynamic solvation at their function sites is critical to the understanding of their electron-transfer properties. Here, we report our complete characterization of the function-site solvation of holoflavodoxin in three redox states and of the binding-site solvation of apoflavodoxin. Using intrinsic flavin cofactor and tryptophan residue as the local optical probes with two site-specific mutations, we observed distinct ultrafast solvation dynamics at the function site in the three states and at the related recognition site of the cofactor, ranging from a few to hundreds of picoseconds. The initial ultrafast motion in 1-2.6 ps reflects the local water-network relaxation ...

This study is a collaborative effort between researchers from Imperial College and the University of Essex, led by emeritus biochemistry Professor Michael Wilson and is an in vitro analysis of the oxidation of the Arabidopsis cryptochrome (CRY) photoreceptor in the presence and absence of an external electron donor. They show that a more complex model than previously thought is required to explain the mechanism by which the CRY-associated flavin molecule is oxidised. The authors propose that the final steps in this reaction require cooperative interaction between partners in a CRY homodimer or between separate CRY molecules..

Essential gene studies often reveal novel essential functions for genes with dispensable homologues in other species. This is the case with the widespread family of electron transfer flavoproteins (ETFs), which are required for the metabolism of specific substrates or for symbiotic nitrogen fixation in some bacteria. Despite these non-essential functions high-throughput screens have identified ETFs as putatively essential in several species. In this study, we constructed a conditional expression mutant of one of the ETFs in Burkholderia cenocepacia, and demonstrated that its expression is essential for growth on both complex media and a variety of single-carbon sources. We further demonstrated that the two subunits EtfA and EtfB interact with each other, and that cells depleted of ETF are non-viable and lack redox potential. These cells also transition from the short rods characteristic of Burkholderia cenocepacia to small spheres independently of MreB. The putative membrane partner ETF dehydrogenase
Here, we show that the Neurospora protein VVD is a blue light photoreceptor. Following the heterologous expression in E.coli, VVD was found to be associated with a flavin‐type chromophore (Figure 3). Upon illumination, the native VVD protein underwent a blue light‐induced absorbance change that was fully reversible in the dark (Figure 4). This photocycle was also reported for the LOV domains of the plant blue light photoreceptor phototropin and indicates the formation of a reversible covalent bond between the conserved cysteine in the VVD LOV domain and the flavin chromophore (Briggs and Christie, 2002). The formation of the cysteinyl‐flavin adduct results in subtle structural changes of the flavin‐binding pocket (Crosson and Moffat, 2002). The latter changes are thought to represent the initial event in light signal transduction and seem to lead to the activation of the intra‐molecular kinase in phototropins. However, VVD is different in this respect since it only contains the LOV ...
We isolated and characterized mouse photolyase-like genes, mCRY1 (mPHLL1) and mCRY2 (mPHLL2), which belong to the photolyase family including plant blue-light receptors. The mCRY1 and mCRY2 genes are located on chromosome 10C and 2E, respectively, and are expressed in all mouse organs examined. We raised antibodies specific against each gene product using its C-terminal sequence, which differs completely between the genes. Immunofluorescent staining of cultured mouse cells revealed that mCRY1 is localized in mitochondria whereas mCRY2 was found mainly in the nucleus. The subcellular distribution of CRY proteins was confirmed by immunoblot analysis of fractionated mouse liver cell extracts. Using green fluorescent protein fused peptides we showed that the C-terminal region of the mouse CRY2 protein contains a unique nuclear localization signal, which is absent in the CRY1 protein. The N-terminal region of CRY1 was shown to contain the mitochondrial transport signal. Recombinant as well as native CRY1
Genetic variations in circadian clock genes may serve as molecular adaptations, allowing populations to adapt to local environments. Here, we carried out a survey of genetic variation in Drosophila cryptochrome (cry), the flys dedicated circadian photoreceptor. An initial screen of 10 European cry alleles revealed substantial variation, including seven non-synonymous changes. The SNP frequency spectra and the excessive linkage disequilibrium in this locus suggested that this variation is maintained by natural selection. We focused on a non-conservative SNP involving a leucine - histidine replacement (L232H) and found that this polymorphism is common, with both alleles at intermediate frequencies across 27 populations surveyed in Europe, irrespective of latitude. Remarkably, we were able to reproduce this natural observation in the laboratory using replicate population cages where the minor allele frequency was initially set to 10%. Within 20 generations, the two allelic variants converged to ...
Birds use the magnetic field of the Earth to navigate during their annual migratory travel. The possible mechanism to explain the biophysics of this compass sense involves electron transfers within the photoreceptive protein cryptochrome. A study (Qin et al., 2016) claimed that the sensitivity to changes in the magnetic field is enhanced by a coupling to an iron rich polymer complex which couples to multiple cryptochromes. For the iron sulphur clusters to participate in the compass sense, they either need to donate an electron to a specific tryptophane in the cryptochome or accept an electron from the flavin adenine dinucleotide (FAD) co-factor in the cryptochrome. To validate the claim, it is needed to independently reconstruct this complex and describe its interaction with Drosophila melanogaster cryptochromes. The polymer complex consists of iron sulphur containing assembly ISCA1 protein monomers with internally bound iron sulphur clusters and simultaneously binds ten cryptochromes, shown in ...

Cryptochromes, Cry, are photoreceptors that absorb blue light and mediate signaling events to modulate a wide range of biological functions such as circadian entrainment and phototropism. The signaling activation is triggered by excitation of the flavin adenine dinucleotide cofactor, followed by protein conformational changes that mediate protein-protein interaction with downstream partners. In this presentation, I will discuss the conditions and functional dynamics of drosophila cryptochrome through a plethora of molecular dynamics simulation and analysis tools. Our model recapitulates various experimental evidence of dCry activation, and the mechanism may be applicable to other cryptochromes.. ...

The Drosophila melanogaster circadian clock is generated by interlocked feedback loops, and null mutations in core genes such as period and timeless generate behavioral arrhythmicity in constant darkness. In light-dark cycles, the elevation in locomotor activity that usually anticipates the light on or off signals is severely compromised in these mutants. Light transduction pathways mediated by the rhodopsins and the dedicated circadian blue light photoreceptor cryptochrome are also critical in providing the circadian clock with entraining light signals from the environment. The cryb mutation reduces the light sensitivity of the flys clock, yet locomotor activity rhythms in constant darkness or light-dark cycles are relatively normal, because the rhodopsins compensate for the lack of cryptochrome function. Remarkably, when we combined a period-null mutation with cryb, circadian rhythmicity in locomotor behavior in light-dark cycles, as measured by a number of different criteria, was restored. ...
Organisms have evolved extensive sensory mechanisms to perceive information carried by light. Their responses are mediated by photoreceptor proteins, which are sensitive to light through prosthetic chromophore molecules. The past decade has witnessed the discovery of a large number of novel flavin-binding photoreceptors, notably the phototropins, the cryptochromes, and BLUF (blue-light sensing using FAD) domains (1). Phototropins are primarily found in plants and control several physiological responses such as phototropism, chloroplast movement, and stomatal opening (2), whereas cryptochromes are known to regulate growth and development in plants and circadian rhythms in plants and insects (3, 4). BLUF domains are a distinct family of flavin-binding photoreceptors that show no significant relationship to other sensor proteins in sequence or structure. The BLUF domain was first discovered as the N-terminal part of the flavoprotein AppA from the purple photosynthetic bacterium Rhodobacter ...
Mazzotta GM, Bellanda M, Minervini G, Damulewicz M, Cusumano P, Aufiero S, Stefani M, Zambelli B, Mammi S, Costa R, Tosatto SCE.. Frontiers in Molecular Neuroscience, 2018. Light is the main environmental stimulus that synchronizes the endogenous timekeeping systems in most terrestrial organisms. Drosophila cryptochrome (dCRY) is a light-responsive flavoprotein that detects changes in light intensity and wavelength around dawn and dusk. We have previously shown that dCRY acts through Inactivation No Afterpotential D (INAD) in a light-dependent manner on the Signalplex, a multiprotein complex that includes visual-signaling molecules, suggesting a role for dCRY in fly vision. Here, we predict and demonstrate a novel Ca2+-dependent interaction between dCRY and calmodulin (CaM). Through yeast two hybrid, coimmunoprecipitation (Co-IP), nuclear magnetic resonance (NMR) and calorimetric analyses we were able to identify and characterize a CaM binding motif in the dCRY C-terminus. Similarly, we also ...

A McCree study in 1972 studied the relative quantum yields of the photosynthetic spectrum and found that a mixture of light, with large quantities of green, produced the most photosynthetic output. However, later research found that photo pigments within the plant tissue absorb this green light and excite/de-excite out other photons such as red or blue. This means that a larger spectrum of light is used by plant, equating to the entire visible spectrum. Therefore, there is no such thing as waste light within the visible spectrum. However, the distribution of the delivered spectrum does heavily influence growth patterns.. Moreover, green light works in some plants to tell it that it is surrounded by other plants and needs a longer stem to break out, typically using the phytochrome mechanism, as does red and far-red light. Cryptochromes are also stimulated by green light to some degree, sometimes reversing blue light driven elongation inhibitory action (see article blue and red light). Due to ...
