Entry Name | BARS_ARATH |
Sequence Status | reviewed |
Protein Name | Alpha-barbatene synthase (AtBS) (EC 4.2.3.69) (Beta-chamigrene synthase) (EC 4.2.3.78) (Terpeneoid synthase 11) (AtTPS11) (Thujopsene synthase) (EC 4.2.3.79) |
Sequence Length | 557 |
Gene Name | BS TPS11 At5g44630 K15C23.7 |
Organism | Arabidopsis thaliana (Mouse-ear cress) |
EC Number | 4.2.3.69; 4.2.3.78; 4.2.3.79 |
Protein Function | FUNCTION: Involved in the biosynthesis of over 15 sesquiterpenes (C15). The major products are (+)-alpha-barbatene (27.3%), (+)-thujopsene (17.8%) and (+)-beta-chamigrene (9.9%). Can use farnesyl diphosphate or geranyl diphosphate as substrates, but not geranylgeranyl diphosphate. {ECO:0000269|PubMed:15918888, ECO:0000269|PubMed:15965019}. |
Pathway | PATHWAY: Secondary metabolite biosynthesis; terpenoid biosynthesis. |
