Pentacyclic triterpene acids (PTAs) are specialized plant metabolites known for their anti-inflammatory and antidiabetic preclinical reports. Cecropia angustifolia , a prominent species in the Andean montane forests, produces a variety of PTAs in its roots, but little is known about enzymes responsible for their oxidative structural decorations. In this study, we explored the biosynthetic route of PTAs oxidation by cytochrome...
