Outline of Research at the Start

植物細胞壁成分ペクチンの生合成には30種類程度の糖転移酵素が関わるとされているが、ほとんどが未同定のままで、ペクチンの生理機能解析が遅れている。ペクチンの主鎖や側鎖形成に関わる4種類の糖転移酵素について、申請者が構築してきたペクチン生合成糖転移酵素遺伝子の同定法を適用し、それらの酵素の基質調製、酵素活性測定、シロイヌナズナゲノムから候補遺伝子の選定、リコンビナント候補タンパク質の酵素活性測定を行い、4種類のペクチン生合成糖転移酵素遺伝子を同定する。さらに、これらの遺伝子発現抑制変異シロイヌナズナを解析し、ペクチンの生理的役割(細胞接着、細胞壁構築による植物体の強度形成など)を明らかにする。

Outline of Final Research Achievements

The aim of the project was to characterize enzymes involved in biosynthesis of plant cell wall pectin. In this study, glycosyltransferases and acetyltransferases involved in pectin biosynthesis were characterized. The galacturonosyltransferases involved in the synthesis of the pectic rhamnogalacturonan I (RG-I) were found to have eight genes in the Arabidopsis genome. The galactoryltransferase involved in synthesis of RG-I side chain was detected for the first time and given the enzyme number EC 2.4.1.375. The enzymatic activity of RG-I: acetyltransferase was detected for the first time in TBL7. In addition, a substrate for RG-II: Kdo transferase, CMP-Kdo, was prepared.

Academic Significance and Societal Importance of the Research Achievements

植物細胞壁ペクチンのいくつかの生合成酵素を解析・遺伝子同定した本研究成果は、ペクチンの機能解析に役立てられる。ペクチンの機能として考えられている細胞接着・形態形成・硬軟調節などに焦点を当て、本研究で同定したペクチン生合成酵素遺伝子を用いて、機能解析を進めることができるようになる。また、ペクチンがヒトの免疫機能を活性化すると考えられており、本研究成果により、ペクチンのどの構造がその機能に関与するか明らかにする研究を展開できる。
