OX NCBI_TaxID=3348; RN [1] RP NUCLEOTIDE SEQUENCE [MRNA], FUNCTION, CATALYTIC ACTIVITY, AND RP BIOPHYSICOCHEMICAL PROPERTIES. RX PubMed=7698342; DOI=10.1016/0014-5793(95)00199-J; RA Raiber S., Schroeder G., Schroeder J.; RT "Molecular and enzymatic characterization of two stilbene synthases RT from Eastern white pine (Pinus strobus). A single Arg/His difference RT determines the activity and the pH dependence of the enzymes."; RL FEBS Lett. 361:299-302(1995). CC -!- FUNCTION: Catalyzes the production of pinosylvin from cinnamoyl- CC CoA and malonyl-CoA, and dihydropinosylvin from dihydrocinnamoyl- CC CoA. {ECO:0000269|PubMed:7698342}. CC -!- CATALYTIC ACTIVITY: 3 malonyl-CoA + cinnamoyl-CoA = 4 CoA + CC pinosylvin + 4 CO(2). {ECO:0000269|PubMed:7698342}. CC -!- CATALYTIC ACTIVITY: 3 malonyl-CoA + dihydrocinnamoyl-CoA = 4 CoA + CC dihydropinosylvin + 4 CO(2). {ECO:0000269|PubMed:7698342}. CC -!- BIOPHYSICOCHEMICAL PROPERTIES: CC pH dependence: CC Optimum pH is 6. {ECO:0000269|PubMed:7698342}; CC -!- PATHWAY: Phytoalexin biosynthesis; pinosylvin biosynthesis. CC -!- SUBUNIT: Homodimer. {ECO:0000250}. CC -!- SUBCELLULAR LOCATION: Cytoplasm. CC -!- INDUCTION: By stress. CC -!- MISCELLANEOUS: STS1 has only 3-5% of the activity of STS2 and CC synthesizes a second unknown product with cinnamoyl-CoA. CC {ECO:0000269|PubMed:7698342}. CC -!- SIMILARITY: Belongs to the chalcone/stilbene synthases family. CC {ECO:0000305}.
