Neocarzilins (NCZs) are antitumor chlorinated polyenones produced by "Streptomyces carzinostaticus" var. F-41. The gene cluster responsible for the biosynthesis of NCZs was cloned and characterized. DNA sequence analysis of a 33-kb region revealed...
Overexpression of the landomycin glycosyltransferase gene lanGT4 in Streptomyces fradiae Tu2717 resulted in the conversion of the urdamycin trisaccharide into an unnatural tetrasaccharide by transfer of an L-rhodinose unit. We propose that LanGT4 ...
A review on biosynthetic studies of the antibiotic actinorhodin and structurally related benzoisochromanequinone. The metabolic engineering is described of deoxysugar moieties of polyketide glycosides, focusing on urdamycins (URDs) from <I>S...
A novel shunt product was isolated from a disruptant of the actVI-ORFA gene involved in the biosynthesis of actinorhodin (ACT) in Streptomyces coelicolor A3(2). Its structure was elucidated as 1,4-naphthoquinone-8-hydroxy-3-[3(S)-acetoxy-butyric a...
