GN Name=STS1; OS Pinus strobus (Eastern white pine). OC Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; OC Spermatophyta; Coniferopsida; Coniferales; Pinaceae; Pinus; Strobus. OX NCBI_TaxID=3348; RN [1] RP NUCLEOTIDE SEQUENCE. RX MEDLINE=95212569; 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: STS1 has only 3-5% of the activity of STS2 and CC synthesizes a second unknown product with cinnamoyl-CoA. CC -!- CATALYTIC ACTIVITY: 3 malonyl-CoA + cinnamoyl-CoA = 4 CoA + CC pinosylvin + 3 CO(2). CC -!- BIOPHYSICOCHEMICAL PROPERTIES: CC pH dependence: CC Optimum pH is 6; CC -!- PATHWAY: Stilbene-type phytoalexins biosynthesis. CC -!- SUBUNIT: Homodimer (By similarity). CC -!- SUBCELLULAR LOCATION: Cytoplasmic. CC -!- INDUCTION: By stress. CC -!- SIMILARITY: Belongs to the chalcone/stilbene synthases family.
