人血小板胞质和纯化的血小板β/γ-肌动蛋白中产气荚膜梭菌iota毒素ADP-核糖基化肌动蛋白的酶活性成分ia,与已报道的肉毒杆菌C2毒素成分I类似。 0.1 mM 鬼笔环肽抑制任一毒素对胞质和纯化肌动蛋白的 ADP 核糖基化,表明单体 G 肌动蛋白而非聚合 F 肌动蛋白是毒素底物。产气荚膜毒素和肉毒杆菌C2毒素不累加血小板肌动蛋白的ADP-核糖基化。用肉毒杆菌 C2 毒素处理完整鸡胚细胞可减少随后产气荚膜杆菌或肉毒杆菌 C2 毒素对细胞裂解物中肌动蛋白的 ADP-核糖基化。与肉毒杆菌 C2 毒素相比,产气荚膜杆菌 iota 毒素 ADP-核糖基化骨骼肌 α-肌动蛋白,其效力和效率与非肌肉肌动蛋白相似。产气荚膜杆菌毒素对纯化的骨骼肌和非肌肉肌动蛋白进行 ADP 核糖基化,导致肌动蛋白聚合能力出现剂量依赖性损害。
The enzymatically active component ia of Clostridium perfringens iota toxin ADP-ribosylated actin in human platelet cytosol and purified platelet beta/gamma-actin, in a similar way to that been reported for component I of botulinum C2 toxin. ADP-ribosylation of cytosolic and purified actin by either toxin was inhibited by 0.1 mM phalloidin indicating that monomeric G-actin but not polymerized F-actin was the toxin substrate. Perfringens iota toxin and botulinum C2 toxin were not additive in ADP-ribosylation of platelet actin. Treatment of intact chicken embryo cells with botulinum C2 toxin decreased subsequent ADP-ribosylation of actin in cell lysates by perfringens iota or botulinum C2 toxin. In contrast to botulinum C2 toxin, perfringens iota toxin ADP-ribosylated skeletal muscle alpha-actin with a potency and efficiency similar to non-muscle actin. ADP-ribosylation of purified skeletal muscle and non-muscle actin by perfringens iota toxin led to a dose-dependent impairment of the ability of actin to polymerize.
