Web1 Feb 2024 · Then, scopoletin can be hydroxylated by SCOPOLETIN 8-HYDROXYLASE (S8H), which yields the coumarin fraxetin [60, 61]. Finally, coumarin sideretin is produced via oxidation of fraxetin by the cytochrome P450 enzyme CYP82C4 [62]. The COSY enzyme catalyzes the conversion of 6’-hydroxy-caffeoyl-CoA to the coumarin esculetin [59].
