Research subject summary

  • 光合成生物は、太陽光を利用して光化学反応を行うために「光捕集アンテナ」と呼ばれる色素タンパク質複合体を利用します。これが「光エネルギーの適切な配分=調節」を行なっていることが次第に明らかになってきました。私は、海洋性の光合成生物の「緑色光を吸収し、効率よく光合成に利用する光捕集アンテナ」のX線結晶構造解析による構造解明と分光学的手法によるエネルギー伝達・散逸機構の解明に取り組んでいます。また、リコンビナント蛋白質と色素による再構成、多孔質シリカや脂質膜内への導入といった色素の周辺環境の制御による物性の改変にも取り組んでいます。この「光捕集アンテナ」における色素の役割と分子メカニズムを解明する事により、太陽光を用いて燃料を生産する「人工光合成」に資する研究を行っていきます。

    MXenes, a new family of 2D nanostructured materials, have been widely studied in the field of artificial photosynthesis due to their outstanding physicochemical properties. In this work, a series of 2,4-bis[4-(N,N-dibutylamino)phenyl] squaraine (SQ) derivatives with different number of hydroxyl groups were hybridized with Ti3C2Tx MXene nanosheets, and the organic-inorganic hybrid photocatalysts were applied for water-splitting hydrogen evolution. The mass ratios of SQ@Ti3C2Tx were optimized to 4 wt% for each SQ, and the best hydrogen evolution reaction (HER) rate of 28.6 μmol h-1 g-1 was achieved by SQ-3 with four OH groups. The photocatalytic ability of the hybrid comes from the outstanding light harvesting of SQ dye, sufficient active sites of Ti3C2Tx, and efficient separation and transfer of the photogenerated charges via heterojunction between SQ aggregates and Ti3C2Tx. This work firstly demonstrates an example of SQ sensitizer combined with MXene for hydrogen generation, which provides a new insight to further explore the MXene-based hybrid nanomaterials for water splitting hydrogen evolution.

    The reassociation of carotenoids with the photosynthetic light-harvesting 1 (LH1) pigment–protein complex has proven to be a powerful technique to investigate the function of carotenoids. We have recently investigated the reassociation of the carotenoids, spirilloxanthin (number of conjugated C=C bonds (<i>n</i>) = 13), anhydrorhodovibrin (<i>n</i> = 12), rhodopin (<i>n</i> = 11), and spheroidene (<i>n</i> = 10)) with carotenoid-depleted LH1 subunits isolated from <i>Rhodospirillum rubrum</i>. In the case of the rhodopin complex, small anomalies were observed in the absorption maximum of the Q<i><sub>y</sub></i> band of bacteriochlorophyll <i>a</i> (BChl <i>a</i> Q<i><sub>y</sub></i>) and the singlet–singlet energy-transter efficiency of <sup>1</sup>carotenoid<sup>*</sup> → <sup>1</sup>BChl <i>a</i><sup>*</sup> within the LH1–carotenoid complex. The reason for these anomalies could probably be ascribed to the rhodopin hydroxy group. To investigate this further, reassociation experiments of the LH1 complex with hydroxy-protected rhodopin, all-<i>trans</i>-3,4-dihydroanhydrorhodovibrin (<b>1</b>), were conducted. We observed a normal absorption maximum (883 nm) of the BChl <i>a</i> Q<i><sub>y</sub></i> band in the LH1–<b>1</b> complex. The energy-transter efficiency of <sup>1</sup>carotenoid<sup>*</sup> (<sup>1</sup><b>1</b><sup>*</sup>) → <sup>1</sup>BChl <i>a</i><sup>*</sup> was found to be 53%, giving a good correlation with the other carotenoids. Furthermore, we found a preferential complexation of all-<i>trans</i>-<b>1</b> to carotenoid-depleted LH1 from a 1:1 mixture of all-<i>trans</i>-<b>1</b> and <i>cis</i>-<b>1</b> (<i>cis</i>-<b>1</b> consists of a 1:1 mixture of 5-<i>cis</i>-5′-<i>trans</i>-<b>1</b> and 5-<i>trans</i>-5′-<i>cis</i>-<b>1</b>).

    In order to clarify the structure-function relationship of carotenoids bound to the LH1 antenna pigment-protein complex, we studied the re-association between synthetic carotenoids and carotenoid-depleted LH1. The spectroscopic properties of the re-associated complexes and the energy transfer efficiency from carotenoids to BChl <I>a</I> were clarified and discussed in comparison to previous experiments. Moreover, we studied the selectivity of carotenoids in the LH1 complex formation.

    海洋性緑藻には、シフォナキサンチンという抗肥満作用を含む薬効を持つ特殊なカロテノイドを含むものがある。中でも食経験のあるミル類について、陸上養殖技術により、微細な糸状の状態で集積培養することに成功している。この糸状体は重量当たりのシフォナキサンチン濃度が高いことがわかっている。これを用いることで、独特のスポンジのような食感を抑え、美味しく食べる方法を開発する。そのほかの生活習慣病の予防効果についても検討し、食品としての価値を探求する。
