The anticancer agent oximidine I and three novel variants were discovered as products of a cryptic trans-AT PKS/NRPS in Pseudomonas baetica. By manipulating the biosynthetic pathway, a key intermediate was identified that retains potent anticancer properties. A combination of bioinformatics analysis and genetic and biochemical experiments illuminated the oximidine biosynthetic pathway, including a novel mechanism for O-methyloxime formation.
