   4.2.3.104 | metabolism |
alpha-humulene synthase is a key enzyme of zerumbone biosynthesis |
718244 |
| 4.2.3.104 | metabolism |
the enzyme is involved in the biosynthetic pathways for sesquiterpenes found in agarwood and cell suspension cultures, putative pathway, overview. Various post-transcriptional, translational, or post-translational regulatory mechanisms affecting the expression or activity of alpha-humulene and delta-guaiene synthases are possible |

| 4.2.3.104 | more |
sesquiterpene synthase alpha-humulene synthase (HUM) from Zingiber zerumbet is investigated for the bioconversion of the monoterpene precursors geranyl diphosphate (2E-GPP) and neryl diphosphate (2Z-NPP) as well as for the sesquiterpene precursor farnesyl diphosphate (2E,6E-FPP) |

| 4.2.3.104 | physiological function |
after tobacco rattlevirus-based virus induced gene silencing, beta-elemene, guaia-1(5),11-diene and guaia-1(10),11-diene are undetectable in suppressed leaves |

| 4.2.3.104 | physiological function |
alpha-humulene is a common sesquiterpene widely distributed in plants, the synthase from Zingiber zerumbet is the only known sesquiterpene synthase to date catalyzing the formation of alpha-humulene as major product |
