多毒素D是一种真菌几丁质合成酶的特异性抑制剂。作为一种核苷二肽抗生素，多毒素D，链霉菌cacaoi变种。asoensis是研究比较尼可霉素Z。多毒素D，链霉菌cacaoi变种。asoensis表现为一个强有力的，竞争性的酶活性抑制剂。在灰双歧杆菌微粒体中，多毒素D，链霉菌cacaoi变种asoensis能够抑制几丁质合成酶，K | i |值为6µM。多毒素D，链霉菌cacaoi变种asoensis也影响芽管，改变其形态并抑制孢子萌发。 Polyoxin D, Streptomyces cacaoi var. asoensis is a specific inhibitor of fungal chitin synthetase. As a nucleoside-dipeptide antibiotic, Polyoxin D, Streptomyces cacaoi var. asoensis is studied comparatively to nikkomycin Z. Polyoxin D, Streptomyces cacaoi var. asoensis behaves as a potent, competitive inhibitor of enzyme activity. In B. cinerea microsomes, Polyoxin D, Streptomyces cacaoi var. asoensis was able to inhibit chitin synthase with a K|i|value of 6 μM. Polyoxin D, Streptomyces cacaoi var. asoensis also affects germ tubes, altering their morphology and inhibiting spore germination.
