Research Abstract

レクチンの一種であるConcanavalin Aの蛍光標識物(ConA-TMR)を用いることにより、枯草菌の細胞壁テイコ酸(WTA)を特異的に検出する方法を確立した。種々のテイコ酸修飾遺伝子変異株を用いて観察を行った結果、ConA-TMRはmajor WTAのグルコース修飾を効率よく検出し、minor WTAやリポテイコ酸は検出できないことが明らかになった。また、major WTAのグルコース修飾に関与するtagE条件変異株を用いて、細胞側壁におけるWTA修飾が螺旋状に行われていることを明らかにした。さらに側壁のWTA修飾制御には、細胞骨格蛋白質のひとつであるMreBが関与している可能性が示唆された。
