Functional Characterization of an Aldol Condensation Synthase PheG for the Formation of Hispidin from Phellinus Igniarius.

Hispidin (1) is a polyphenolic compound with a wide range of pharmacological activities that is distributed in both plants and fungi. In addition to natural extraction, hispidin can be obtained by chemical or enzymatic synthesis. In this study, the identification and characterization of an undescribed enzyme, PheG, from Phellinus igniarius (P.
