How to use
In Vitro:
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.
