ascamycin 性质
Ascamycin 是一种由链霉菌属 (Streptomyces sp. JCM9888) 产生的 5'-O-磺酰胺核糖核苷抗生素。Ascamycin 对 Xanthomonas 菌具有选择性的抑菌活性，对 Xanthomonas citri，Xanthomonas oryzae 和 Mycobacterium phlei 的 MIC 值分别为 0.4 μg/mL，12.5 μg/mL 和 12.5 μg/mL。
MIC: 0.4 μg/mL ( Xanthomonas citri ), 12.5 μg/mL ( Xanthomonas oryzae ) and 12.5 μg/mL ( Mycobacterium phlei )
The Ascamycin has C2-chloroadenine as the base on C-1' which lacks the chlorine. Ascamycin has a selective antibacterial activity against Xanthomonas species. When Ascamycin is dealanylated, Dealanylascamycin shows a broad antibacterial activity against various Gram-negative and Gram-positive bacteria. Xanthomonas citri is susceptible to Ascamycin by virtue of the Ascamycin-dealanylating enzyme on the cell surface.
