CC -!- FUNCTION: Type III polyketide synthase involved in the biosynthesis of
CC benzophenones and xanthones. Produces mainly 2,4,6-
CC trihydroxybenzophenone together with minor amounts of tetraketide
CC lactone, triketide lactone and diketide lactone. The preferred
CC substrate is benzoyl-CoA, but can also use acetyl-CoA, phenylacetyl-
CC CoA, hexanoyl-CoA, cinnamoyl-CoA, p-coumaroyl-CoA and salicoyl-CoA.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=benzoyl-CoA + 2 H(+) + 3 malonyl-CoA = 2,4,6-
CC trihydroxybenzophenone + 3 CO2 + 4 CoA; Xref=Rhea:RHEA:35143,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:16526, ChEBI:CHEBI:57287,
CC ChEBI:CHEBI:57369, ChEBI:CHEBI:57384, ChEBI:CHEBI:77765;
CC EC=2.3.1.220; Evidence={ECO:0000269|PubMed:22390826};
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=9.65 uM for benzoyl-CoA {ECO:0000269|PubMed:22390826};
CC KM=16.38 uM for malonyl-CoA {ECO:0000269|PubMed:22390826};
CC Note=kcat is 2.97 min(-1) with benzoyl-CoA as substrate. kcat is 3.49
CC min(-1) with malonyl-CoA as substrate.;
CC pH dependence:
CC Optimum pH is 6.5-7.0. {ECO:0000269|PubMed:22390826};
CC Temperature dependence:
CC Optimum temperature is 30 degrees Celsius.
CC {ECO:0000269|PubMed:22390826};
CC -!- SUBUNIT: Homodimer. {ECO:0000269|PubMed:22390826}.
CC -!- TISSUE SPECIFICITY: Expressed in young fruit pericarp.
CC {ECO:0000269|PubMed:22390826}.
CC -!- SIMILARITY: Belongs to the thiolase-like superfamily. Chalcone/stilbene
CC synthases family. {ECO:0000305}.
