Marneral synthase (EC 5.4.99.53) is an enzyme with systematic name (3S)-2,3-epoxy-2,3-dihydrosqualene mutase (cyclizing, marneral-forming).[1] This enzyme catalyses the following chemical reaction
- (3S)-2,3-epoxy-2,3-dihydrosqualene [math]\displaystyle{ \rightleftharpoons }[/math] marneral
Marneral is a triterpenoid formed by Grob fragmentation of the A ring of 2,3-epoxy-2,3-dihydrosqualene during cyclization. This aldehyde gains its name from its structural similarity to a class triterpenes commonly found in members of the Iridaceae, originally identified by Dr. Franz-Josef Marner[1]
This enzyme is a member of a metabolic gene cluster along with two other cytochrome P450s.[2]
