Characterization of cytochrome P450 monooxygenase gene gonCP. a UPLC analysis of PM100117 (1) and PM100118 (2) production in Streptomyces caniferus GUA-06-05-006A wild type (GUA) and ΔgonCP mutant. Peaks with an absorption spectrum related to PM100117 and PM100118 derivatives are tagged with triangles. b Chemical structures of PM100117 and PM100118 derivatives lacking a keto functional group of the macrolactone moiety. Asterisks indicate the point where the PM100117 and PM100118 chemical structures have been modified
