SQE1

Gene
SQE1
Protein
Squalene monooxygenase SE1
Organism
Panax ginseng
Length
539 amino acids
Function
Component of the triterpene saponins (e.g. ginsenosides or panaxosides) and phytosterols biosynthetic pathways (PubMed:19857882, PubMed:27746309, PubMed:29378087). Catalyzes the first oxygenation step in sterol biosynthesis and is suggested to be one of the rate-limiting enzymes in this pathway (By similarity).
Similarity
Belongs to the squalene monooxygenase family.

Gene

Protein
Squalene epoxidase 1
Organism
Arabidopsis thaliana
Length
531 amino acids
Function
Catalyzes the stereospecific oxidation of squalene to (S)-2,3-epoxysqualene, and is considered to be a rate-limiting enzyme in steroid biosynthesis. Can produce not only oxidosqualene, but also 2,3:22,23-dioxidosqualene. Main squalene epoxidase in the root. Sqe1 mutants may show defects in membrane lipid rafts, impairing the correct localization of RHD2 NADPH oxidase and the proper polarized production of ROS.
Similarity
Belongs to the squalene monooxygenase family.
