Molecular cloning, sequence analysis and functional characterization of the gene cluster for biosynthesis of K-252a and its analogs.


Among the indolocarbazole alkaloids of antitumor antibiotics, K-252a represents a structurally unique indolocarbazole glycoside and exhibits potent neuroprotective and broad anticancer activities. K-252a consists of K-252c and the unusual dihydrostreptose moiety, linked together with oxidative and glycosidic C-N bonds. Herein, we reported a complete… (More)
