    Abstract

    Cyanobacteria inhabit areas with a broad range of light, temperature and nutrient conditions. The robustness of cyanobacterial cells, which can survive under different conditions, may depend on the resilience of photosynthetic activity. Cyanothece sp. PCC 8801 (Cyanothece), a freshwater cyanobacterium isolated from a Taiwanese rice field, had a higher repair activity of photodamaged photosystem II (PSII) under intense light than Synechocystis sp. PCC 6803 (Synechocystis), another freshwater cyanobacterium. Cyanothece contains myristic acid (14:0) as the major fatty acid at the sn-2 position of the glycerolipids. To investigate the role of 14:0 in the repair of photodamaged PSII, we used a Synechocystis transformant expressing a T-1274 encoding a lysophosphatidic acid acyltransferase (LPAAT) from Cyanothece. The wild-type and transformant cells contained 0.2 and 20.1 mol% of 14:0 in glycerolipids, respectively. The higher content of 14:0 in the transformants increased the fluidity of the thylakoid membrane. In the transformants, PSII repair was accelerated due to an enhancement in the de novo synthesis of D1 protein, and the production of singlet oxygen (1O2), which inhibited protein synthesis, was suppressed. The high content of 14:0 increased transfer of light energy received by phycobilisomes to PSI and CP47 in PSII and the content of carotenoids. These results indicated that an increase in 14:0 reduced 1O2 formation and enhanced PSII repair. The higher content of 14:0 in the glycerolipids may be required as a survival strategy for Cyanothece inhabiting a rice field under direct sunlight.

    AbstractPhotophysical properties of benzil (1,2-diphenylethane-1,2-dione) and its derivatives in the crystal state have recently attracted much attention. However, the study of substituted benzils has mostly been limited to para-substituted derivatives, which did not induce a significant effect on the emission wavelength compared to pristine benzil. The effects of ortho- and meta-substituents on the photophysical properties in the crystal state have not been investigated so far. Our recently developed organocatalytic pinacol coupling of substituted benzaldehydes allowed us to prepare various ortho-, meta-, and para-substituted benzil derivatives and to investigate their luminescence properties. Ortho- and meta-substituents affected the electronic states of benzils in the crystal state, resulting in differences in their luminescence properties. The luminescence wavelength and type, i.e., phosphorescence or fluorescence, were altered by these substituents. Fast self-recovering phosphorescence-to-phosphorescence mechanochromism by the para-CF3 substituent at room temperature was also discovered.

  • Acylated plastoquinone is a novel neutral lipid accumulated in cyanobacteria

    Abstract
    Although cyanobacteria do not possess bacterial triacylglycerol (TAG)-synthesizing enzymes, the accumulation of TAGs and/or lipid droplets has been repeatedly reported in a wide range of species. In most cases, the identification of TAG has been based on the detection of the spot showing the mobility similar to the TAG standard in thin-layer chromatography (TLC) of neutral lipids. In this study, we identified monoacyl plastoquinol (acyl PQH) as the predominant molecular species in the TAG-like spot from the unicellular Synechocystis sp. PCC 6803 (S.6803) as well as the filamentous Nostocales sp., Nostoc punctiforme PCC 73102, and Anabaena sp. PCC 7120. In S.6803, the accumulation level of acyl PQH but not TAG was affected by deletion or overexpression of slr2103, indicating that acyl PQH is the physiological product of Slr2103 having homology with the eukaryotic diacylglycerol acyltransferase-2 (DGAT2). Electron microscopy revealed that cyanobacterial strains used in this study do not accumulate lipid droplet structures such as those observed in oleaginous microorganisms. Instead, they accumulate polyhydroxybutyrate (PHB) granules and/or aggregates of alkane, free C16 and C18 saturated fatty acids, and low amounts of TAG in the cytoplasmic area, which can be detected by staining with a fluorescent dye specific to neutral lipids. Unlike these lipophilic materials, acyl PQH is exclusively localized in the membrane fraction. There must be DGAT2-like enzymatic activity esterifying de novo-synthesized C16 and C18 fatty acids to PQH2 in the thylakoid membranes.

    Abstract

    From the reaction of sterically less hindered tetrapropyl[24]dithiaamethyrin(1.0.0.1.0.0) 5, with [Rh(CO)2Cl]2, a unique anti form of the bis(dicarbonylrhodium(I)) complex (6‐anti), where two rhodium ions are on the opposite faces of the macrocyclic ligand, was isolated for the first time in 12% yield along with the corresponding syn isomer (6‐syn, 61% yield). These structures were characterized in detail by single‐crystal X‐ray structure analysis. Compound 6‐syn exhibited a bowl‐shaped structure with the two rhodium atoms separated by a distance of ∼4.5 Å. In contrast, 6‐anti contained a wave‐shaped macrocycle with a distance of ∼5.3 Å between the two rhodium atoms. Furthermore, the 1H nuclear magnetic resonance spectra and density functional theory calculation results revealed that 6‐anti had a stronger paratropic ring current and a more planar structure than 6‐syn. The isolation of both 6‐anti and 6‐syn enabled detailed discussion of the structure‐property relationship.

    A xanthene derivative containing a borinate moiety emitted red fluorescence with a high quantum yield. The interaction between the borinate and a sugar molecule induced a fluorescence change based on the change in the HOMO–LUMO gap. The response was pH-resistant in a wide range. In addition, catechol quenched through photoinduced electron transfer. The red fluorescence and polyol binding ability of dyes will pave the way for new biological applications of chemical sensors.Open Access Article

  • An orthorhombic polymorph ofN1,N4-diphenyl-3,6-bis(phenylimino)cyclohexa-1,4-diene-1,4-diamine

    Acta Crystallographica Section E Structure Reports Online, Volume：70, Number：4, First page：o495, Last page：o496, Mar. 2014
    A new orthorhombic polymorph of the title compound, C30H24N4, with a density of 1.315 Mg m−3, has been obtained. The molecule is centrosymmetric with the centroid of the cyclohexa-1,4-diene ring located on an inversion center. The two unique benzene rings are almost perpendicular to each other [dihedral angle = 86.70 (6)°] and are oriented at dihedral angles of 30.79 (5) and 68.07 (5)° with respect to the central cyclohexadiene ring. In the crystal, π–π stacking is observed between the central cyclohexa-1,4-diene-1,4-diamine unit and a phenyl ring of a neighboring molecule [centroid–centroid distance = 3.7043 (7) Å]. The crystal structure of the triclinic polymorph [Ohnoet al.(2014).Acta Cryst.E70, o303–o304] showed chains running along theb-axis direction through weak C—H...π interactions.

    The preparative conditions and stability of cis-[Co(NO2)4(NH3)2]-, which had been a missing link in the ammine-nitro cobalt(III) series until recently, were studied using 59Co NMR spectroscopy. The reaction of Na3[Co(NO2)6] with liquid ammonia mainly gave cis-[Co(NO2)4(NH3)2]- together with mer- and fac-[Co(NO2)3(NH3)3] and cis-[Co(NO2)2(NH3)4]+; the formation of trans-[Co(NO2)4(NH3)2]- was not observed. The reaction of aqueous [Co(NO2)6]3- with aqueous ammonia also gave the cis isomer as a major product. On the contrary, the cis isomer did not form during the conventional preparation from CoCl2 in an aqueous solution. The cis isomer was very stable in the solid state, but the isomer slowly isomerized in water (t1/2>5 days at room temperature, ca. 0.1mol dm-3) to the trans isomer. The reaction was accompanied by the formation of fac-[Co(NO2)3(NH3)3] which then isomerized to the mer isomer, and by the formation of several unknown species.

    New inorganic-organic hybrid Nanoclusters were synthesized by using Zwitter ionic ligands and various metal ions. The synthesized clusters were clarified about their structures in the solid and in solution, the electrochemical properties, and the spectroscopy characters. The interactions between ligands and metals for multi-electronic redox system of electronic and structural characters were examined based on the obtained results. The electronic state and the analyses of their structures were carried out by also using the computational calculations. The new Zwitter ionic ligands that showed more complex multi electron redox system were developed. The evaluation of their functionality as the Nano-material was tried from these results. Thesis submission was done for a part of the result of obtaining, and the result was made public.
