Abstract

Heat shock treatment of 14-h-old Neurospora crassa mycelium, for 1 h at 48 degrees C, led to the induction of high levels of peroxidase (EC. 1.11.1.7) activity. No significant change was observed in the superoxide dismutase content. Colonies formed by plating conidial suspensions on sorbose-medium also exhibited high peroxidase activity following exposure to hyperthermia and were found to be resistant to normally toxic doses of H2O2. Thus one of the heat shock proteins of N. crassa has the function of protection against oxidative stress.

摘要

对14小时龄的粗糙脉孢菌菌丝体在48摄氏度下进行1小时的热休克处理，导致高水平过氧化物酶（EC. 1.11.1.7）活性的诱导。超氧化物歧化酶含量未观察到显著变化。将分生孢子悬浮液接种在山梨糖培养基上形成的菌落，在暴露于高温后也表现出高过氧化物酶活性，并且发现对正常毒性剂量的H2O2具有抗性。因此，粗糙脉孢菌的一种热休克蛋白具有抵御氧化应激的功能。
