CC -!- FUNCTION: Involved in monoterpene (C10) biosynthesis. The major product
CC is 1,8-cineole (52%) followed by minor amounts of sabinene (14.5%),
CC myrcene (13.3%), (-)-(1S)-beta-pinene (7.8%), (-)-(4S)-limonene (4.0%),
CC (E)-beta-ocimene (2.7%), alpha-terpineol (2.4%), (-)-(1S)-alpha-pinene
CC (1.9%), terpinolene (0.8%), and (+)-alpha-thujene (0.6%).
CC {ECO:0000269|PubMed:15299125}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(2E)-geranyl diphosphate + H2O = 1,8-cineole + diphosphate;
CC Xref=Rhea:RHEA:32543, ChEBI:CHEBI:15377, ChEBI:CHEBI:27961,
CC ChEBI:CHEBI:33019, ChEBI:CHEBI:58057; EC=4.2.3.108;
CC Evidence={ECO:0000269|PubMed:15299125};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250};
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035; Evidence={ECO:0000250};
CC Note=Binds 3 Mg(2+) or Mn(2+) ions per subunit. {ECO:0000250};
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=0.2 uM for geranyl diphosphate {ECO:0000269|PubMed:15299125};
CC Vmax=10.9 pmol/sec/mg enzyme toward geranyl diphosphate
CC {ECO:0000269|PubMed:15299125};
CC pH dependence:
CC Optimum pH is 8.0. {ECO:0000269|PubMed:15299125};
CC -!- PATHWAY: Secondary metabolite biosynthesis; terpenoid biosynthesis.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast {ECO:0000305}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=1;
CC IsoId=P0DI77-1; Sequence=Displayed;
CC Name=2;
CC IsoId=P0DI77-2; Sequence=VSP_044205, VSP_044206;
CC -!- TISSUE SPECIFICITY: Predominantly expressed in roots and at much lower
CC levels in siliques. Not found in leaves, flowers or stems. Also
CC detected in flowers in cv. Landsberg erecta. Not expressed in root
CC apical meristem and elongation zone. Found in the vascular system of
CC young roots and additionally in the cortex and epidermal cell layer of
CC older roots. {ECO:0000269|PubMed:12566586,
CC ECO:0000269|PubMed:15299125}.
CC -!- INDUCTION: Not induces in aerial parts by treatments with jasmonic
CC acid, 6-ethyl indanoyl-L-Ile, fungal peptaibol elicitor alamethicin or
CC herbivory. {ECO:0000269|PubMed:15299125}.
CC -!- DOMAIN: The Asp-Asp-Xaa-Xaa-Asp/Glu (DDXXD/E) motif is important for
CC the catalytic activity, presumably through binding to Mg(2+).
CC -!- MISCELLANEOUS: [Isoform 2]: May be due to intron retention.
CC {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the terpene synthase family. Tpsb subfamily.
CC {ECO:0000305}.
