|Gene:||OSCPNX1||Accession Number: G-10241 (MetaCyc)|
Synonyms: CAS, oxidosqualene cyclase
Species: Panax ginseng
A cDNA was isolated from suspended cells of hairy roots of Panax ginseng. The cDNA was recombinantly expressed in yeast cells and the molecular weight of the protein was calculated to be 86 kDa [Kushiro98]. The protein was shown to catalyze the conversion of (3S)-2,3-epoxy-2,3-dihydrosqualene to cycloartenol [Kushiro98].
Molecular Weight of Polypeptide: 86.0 kD (from nucleotide sequence)
