Trichothecium roseum Lk ex Fr produces simultaneously trichothecin and proteolytic enzymes possessing fibrinolytic, thrombolytic and esterase activity. In addition to the function of splitting and consuming the substrate, the proteolytic enzymes of T. roseum are probably able to hydrolize the other bond in the molecule of trichothecin, which results in partial inactivation of the antibiotic in both the fungus culture and the model experiment on trichothecin contact with the preparations of the proteolytic enzymes. Presence of proteases of T. roseum may be considered as a protective mechanism for detoxication of the metabolites toxic for the organism.
粉红单端孢(Trichothecium roseum Lk ex Fr)同时产生单端孢霉烯毒素和具有纤溶、溶栓及酯酶活性的蛋白水解酶。除了分解和消耗底物的功能外,粉红单端孢的蛋白水解酶可能还能够水解单端孢霉烯毒素分子中的其他键,这导致在真菌培养物以及单端孢霉烯毒素与蛋白水解酶制剂接触的模型实验中,抗生素出现部分失活。粉红单端孢蛋白酶的存在可被视为一种对生物体有毒的代谢产物进行解毒的保护机制。
