   4.2.3.81 | evolution |
the enzyme belongs to the terpene sythase superfamily, subfamily TPS-b. The arginine-tryptophan motif, R(R)X8W, present at the N-terminus of most mono-TPS and in some sesqui-TPS and di-TPS, is found in CoTPS3 |

| 4.2.3.81 | malfunction |
transgenic maize plants overexpressing EREB58 show constitutive overaccumulation of TPS10 transcripts and also two major TPS10 products, (E)-beta-farnesene and (E)-alpha-bergamotene. By contrast, the contents of these two sesquiterpenes are reduced in EREB58-RNAi transgenic lines, in which the expression of TPS10 is suppressed |

| 4.2.3.81 | metabolism |
the enzyme is part of the biosynthesis of volatile organic compounds in flowers |

| 4.2.3.81 | metabolism |
the herbivore-induced sesquiterpenes of maize are mainly produced by two terpene synthases, TPS10 and TPS23, which convert the substrate farnesyl diphosphate (FPP) into various structurally diverse products |

the region from -300 to -200 of the maize TPS10 promoter is both necessary and sufficient for its inducibility by herbivory, the herbivore- and jasmonate-responsive AP2/ERF transcription factor EREB58 is a positive regulator of TPS10 expression and TPS10 volatile emission in maize, and plays a potential role in indirect defense against herbivores in maize, EREB58 binds directly to the GCC-box within the promoter fragment from -300 to -200 and promotes TPS10 expression, phylogenetic analysis, overview |

| 4.2.3.81 | physiological function |
enzyme TPS10 forms (E)-alpha-bergamotene and (E)-beta-farnesene along with 13 minor sesquiterpenes in herbivore-damaged leaves |

| 4.2.3.81 | physiological function |
recombinant CoTPS3 catalysed the conversion of farnesyl pyrophosphate to alpha-bergamotene, from farnesyl diphosphate. The enzyme is part of the biosynthesis of volatile organic compounds (VOCs) in flowers. Floral scents are a key factor in plant-insect interactions and are vital for successful pollination. The scented flowers of Cananga odorata var. fruticosa are analysed by GC-MS and a total of 49 VOCs are identified at four different stages of flower development. The bulk of these VOCs are terpenes, mainly sesquiterpenes |
