Trichoderma reesei cellobiohydrolase I (TrCel7A) molecules were observed to slide unidirectionally along the crystalline cellulose surface, and the catalytic domain without the cellulose-binding domain moved with a velocity similar to that of the intact TrCel7A enzyme although inactive mutant did not move, indicating a processive movement of the enzyme driven by the hydrolytic reaction. We also observed traffic jam of enzyme molecules and synergistic degradation of crystalline cellulose using HS-AFM., 金沢大学ナノ生命科学研究所 / 金沢大学理工研究域数物科学系}, pages = {140--144}, title = {高速原子間力顕微鏡による結晶性セルロース酵素分解のリアルタイム1分子イメージング}, volume = {53}, year = {2013} }
