Abstract

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.

摘要

从镰刀菌属K432菌株培养物中分离得到的镰刀菌素A（FSA）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，我们制备了固定有FSA的亲和凝胶。用这种凝胶进行亲和层析的结果表明，微管蛋白和肌动蛋白是FSA结合蛋白。通过表面等离子体共振光谱法估算了微管蛋白和肌动蛋白对FSA的结合亲和力。
