Function
function
Component of the triterpene saponins (e.g. ginsenosides or panaxosides) and phytosterols biosynthetic pathways (PubMed:27746309, PubMed:29378087).
Catalyzes the biosynthesis of squalene (By similarity).
Catalyzes the biosynthesis of squalene (By similarity).
Catalytic activity
- 2 (2E,6E)-farnesyl diphosphate + H+ + NADH = 2 diphosphate + NAD+ + squaleneThis reaction proceeds in the forward direction.
Cofactor
Mn2+ (UniProtKB | Rhea| CHEBI:29035 )
Pathway
Terpene metabolism; lanosterol biosynthesis; lanosterol from farnesyl diphosphate: step 1/3.
