Fusarielin A (FSA), isolated from culture of Fusarium sp. K432, has anti-fungal/anti-angiogenic activity. Based on our previous structure–activity relationship studies, we prepared FSA-immobilized affinity gel. The results of affinity chromatography with this gel indicated that tubulin and actin are FSA-binding proteins. The binding affinities of tubulin and actin for FSA were estimated by the use of surface plasmon resonance spectroscopy.
Fusarielin A (FSA),从镰刀菌培养物中分离出来。 K432,具有抗真菌/抗血管生成活性。基于我们之前的构效关系研究,我们制备了FSA固定的亲和凝胶。使用该凝胶的亲和层析结果表明微管蛋白和肌动蛋白是FSA结合蛋白。通过使用表面等离振子共振光谱来估计微管蛋白和肌动蛋白对 FSA 的结合亲和力。
