CC -!- FUNCTION: Involved in defensive oleoresin formation in conifers in CC response to insect attack or other injury. Involved in monoterpene CC (C10) olefins biosynthesis. {ECO:0000269|PubMed:10441373, CC ECO:0000269|PubMed:11404343, ECO:0000269|PubMed:9539701}. CC -!- CATALYTIC ACTIVITY: CC Reaction=(2E)-geranyl diphosphate = (1S,4R)-camphene + diphosphate; CC Xref=Rhea:RHEA:25484, ChEBI:CHEBI:89, ChEBI:CHEBI:33019, CC ChEBI:CHEBI:58057; EC=4.2.3.117; CC Evidence={ECO:0000269|PubMed:10441373}; 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 -!- COFACTOR: CC Name=K(+); Xref=ChEBI:CHEBI:29103; Evidence={ECO:0000250}; CC -!- PATHWAY: Terpene metabolism; oleoresin biosynthesis. CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast {ECO:0000250}. 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: The conserved 59-Arg-Arg-60 motif may play a role in the CC isomerization step of the terpenoid cyclization reaction sequence. CC -!- SIMILARITY: Belongs to the terpene synthase family. Tpsd subfamily. CC {ECO:0000305}.
