CC   -!- FUNCTION: Diterpene synthase that catalyzes the formation of (-)-
CC       kolavenyl diphosphate from geranylgeranyl diphosphate (GGPP).
CC       {ECO:0000269|PubMed:26749264}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(2E,6E,10E)-geranylgeranyl diphosphate = (-)-kolavenyl
CC         diphosphate; Xref=Rhea:RHEA:54684, ChEBI:CHEBI:58756,
CC         ChEBI:CHEBI:138310; EC=5.5.1.28;
CC         Evidence={ECO:0000269|PubMed:26749264};
CC       PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:54685;
CC         Evidence={ECO:0000269|PubMed:26749264};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000250|UniProtKB:A0A1S5RW73};
CC   -!- ACTIVITY REGULATION: Inhibited by high concentrations of magnesium.
CC       {ECO:0000250|UniProtKB:A0A1S5RW73}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast {ECO:0000255}.
CC   -!- DOMAIN: The Asp-Xaa-Asp-Asp (DXDD) motif is important for the catalytic
CC       activity through binding to Mg(2+). {ECO:0000305|PubMed:26749264}.
CC   -!- SIMILARITY: Belongs to the terpene synthase family. Tpsc subfamily.
CC       {ECO:0000305}.
