ECC Gene ID Repr. ID Gene name Functional description O.I. H.G. Other DB
XAt1g78960844236ATLUP2Encodes a multifunctional 2-3-oxidosqualene (OS)-triterpene cyclase that can cyclize OS into lupeol, alpha- and beta-amyrin.O.I.H.G.
XAt1g78970844237LUP1 (LUPEOL SYNTHASE 1)Lupeol synthase. Converts oxidosqualene to multiple triterpene alcohols and a triterpene diols. This conversion proceeds through the formation of a 17β-dammarenyl cation.O.I.H.G.
XAt2g07050815275CAS1 (cycloartenol synthase 1)Involved in the biosynthesis of brassinosteroids. Catalyzes the reaction from epoxysqualene to cycloartenol.O.I.H.G.
CAt1g66960843014lupeol synthase, putative / 2,3-oxidosqualene-triterpenoid cyclase, putativeF:lupeol synthase activity;P:pentacyclic triterpenoid biosynthetic process;C:unknown;BPOFMO.I.H.G.
CAt1g78500844186pentacyclic triterpene synthase, putativeEncodes a protein with pentacyclic triterpene synthase activity. In addition to the compounds lupeol, α-amyrin and bauerenol, this enzyme was also shown to produce two seco-triterpenes: α- and β-seco-amyrin.O.I.H.G.
CAt3g45130823649LAS1F:lanosterol synthase activity;P:pentacyclic triterpenoid biosynthetic process;C:cellular_component unknown;BPOFMAO.I.H.G.
CAt4g15370827203BARS1 (BARUOL SYNTHASE 1)Encodes an oxidosqualene cyclase that primarily produces the tetracyclic triterpene baruol in vitro and when expressed in yeast. It can also make 22 other minor triterpenoid products with varying numbers of rings.O.I.H.G.
CAt5g36150833612ATPEN3 (putative pentacyclic triterpene synthase 3)F:lupeol synthase activity, catalytic activity;P:pentacyclic triterpenoid biosynthetic process;C:cellular_component unknown;BPOFMO.I.H.G.
CAt5g42600834267MRN1 (MARNERAL SYNTHASE)Encodes an oxidosqualene synthase that produces the monocyclic triterpene marneral.O.I.H.G.
CAt5g48010834852THAS1 (THALIANOL SYNTHASE 1)Encodes an oxidosqualene cyclase involved in the biosynthesis of thalianol, a tricyclic triterpenoid of unknown function. Overexpression of THAS leads to dwarfing in the aerial tissues of Arabidopsis plants, but increases their root length. THAS is part of a small operon-like cluster of genes (with At5g48000 (THAH) and At5g47990 (THAD)) involved in thalianol metabolism.O.I.H.G.
