IntEnz Enzyme Nomenclature


Accepted name:
dihydromonacolin L hydroxylase
Other name:
LovA [ambiguous]
Systematic name:
dihydromonacolin L acid,[reduced NADPH—hemoprotein reductase]:oxygen oxidoreductase (3-hydroxylating)




A cytochrome P450 (heme-thiolate) protein. The dehydration of 3α-hydroxy-3,5-dihydromonacolin L acid is believed to be spontaneous [1,2]. The enzyme from fungi also catalyses the reaction of EC, monacolin L hydroxylase [3].
