Stilbene Synthase and Chalcone Synthase : Two Different Constitutive Enzymes in Cultured Cells of Picea excelsa.
Cultured cells of Picea excelsa capable of forming stilbenes and flavanoids have been established. Unlike needles of intact plants containing piceatannol (3,3',4',5-tetrahydroxystilbene) and stilbene glycosides the cultured cells converted phenylalanine and p-coumaric acid primarily into resveratrol monomethyl ether (3,4'-dihydroxy-5-methoxystilbene) and naringenin. Partially purified enzyme pr...
متن کاملCross-reaction of chalcone synthase and stilbene synthase overexpressed in Escherichia coli.
Chalcone synthase (CHS) and stilbene synthase (STS) are related plant polyketide synthases belonging to the CHS superfamily. CHS and STS catalyze common condensation reactions of p-coumaroyl-CoA and three C(2)-units from malonyl-CoA but different cyclization reactions to produce naringenin chalcone and resveratrol, respectively. Using purified Pueraria lobata CHS and Arachis hypogaea STS overex...
متن کاملMonoterpene synthase from Dracocephalum kotschyi and SPME-GC-MS analysis of its aroma profile
Dracocephalum kotschyi (Lamiaceae), as one of the remarkable aromatic plants, widely grows and also is cultivated in various temperate regions of Iran. There are diverse reports about the composition of the oil of this plant representing limonene derivatives as its major compounds. There is no report on cloning of mono- or sesquiterpene synthases from this plant. In the present study, ...
متن کاملGenetic analysis of polyketide synthase and peptide synthase genes of cyanobacteria as a mining tool for new pharmaceutical compounds
Cyanobacteria are considered a promising source for new pharmaceutical lead compounds and a large number of chemically diverse and bioactive metabolites have been obtained from cyanobacteria. Despite of several worldwide studies on prevalence of NRPSs and PKSs among the cyanobacteria, none of them included Iranian cyanobacteria of Kermanshah province. Therefore, the aim of this study was t...
متن کاملCystathionine synthase activity in human lymphocytes: induction by phytohemagglutinin.
Uncultured human leukocytes contain no detectable cystathionine synthase activity. A method is described in which the addition of phytohemagglutinin (PHA) to short-term lymphocyte cultures results in a significant induction of enzymatic activity. This PHA-stimulated activity has characteristics that resemble those previously described for cystathionine synthase of normal liver and cultured fibr...
