Cyclic peptide from fungus Alternaria Cyclic peptide from fungus Alternaria Tentoxin was used to eliminate polyphenol oxidase (PPO) activity from seedlings of higher plants
Tentoxin is a majorly occurring cyclic tetrapeptide mycotoxin that is excreted by the Alternaria fungal species like Alternaria alternata and Alternaria tenuis.
生物化学/生理学 作用:它能诱导许多双子叶植物的发芽幼苗发生萎黄病。据推测,腾毒素在 ATP 合成的末端步骤中作为一种能量转移抑制剂,可抑制循环光磷酸化,并以光合 H+-ATP 酶的 F1 分子为目标。有报告称,腾毒素对叶绿体 ATP 合成酶的叶绿体 F1 H+-ATP 酶(CF1)部分的作用进行了动力学分析。它还能通过抑制叶绿体 ATP 合成酶来阻止光磷酸化。它还能抑制叶绿体 ATP 合成酶,从而阻止光磷酸化。在紫外线的照射下,Tentoxin 会使叶绿体过度活跃,并转化成同素异形毒素。
Soluble in methanol, DMSO, water (6 mg/ml, sonification) at 60 °C, DMSO/methanol (10 mg/ml) producing clear colorless solution, and ethanol (10 mg/ml) with heat as needed, yielding a clear, colorless solution.
