Carpropamid ((1RS, 3SR )-2, 2-dichloro-N-
[(R )-1-(4-chlorophenyl)ethyl]-1-ethyl-3-methylcyclopropanecarboxamide) is a potent chemical against the rice blast fungus, Pyricularia oryzae. In 2001, isolates of the fungus with reduced sensitivity to this fungicide appeared in Saga Prefecture of Japan and were regarded as a potential threat to rice protection by carpropamid. The cause of the resistance has been identified genetically as a point mutation resulting in the Val75Met change in scytalone dehydratase, the primary target of the fungicide. We constructed an overexpression system of the variant enzyme and characterized the kinetics in the catalysis and the inhibition by carpropamid isomers. The variant enzyme retained a significant level of enzymatic activity. Inhibition of the variant enzyme by carpropamid was more than 200-fold reduced in comparison with that of the wild-type. Based on the results, here we propose possible mechanisms of the carpropamid-resistance of the variant enzyme in retaining the normal enzymatic activity.

極低温Ｘ線結晶構造解析と分子動力学計算による蛋白質の水和構造解析について最近の知見を平易にまとめた。２つの実験手法は、蛋白質の水和構造についてまったく新しい見方を提供している。特に、結晶解析で見出されたドメイン運動と水和構造変化の協奏や、分子動力学計算で観測される溶媒双極子場は、水溶液中での蛋白質の動力学や相互作用に新たな視点をもたらすものである。
