An in vitro enzyme system for the conversion of amino acid to oxime in the biosynthesis of glucosinolates has been established by the combined use of an improved isolation medium and jasmonic acid-induced etiolated seedlings of Sinapis alba L. An 8-fold induction of de novo biosynthesis of the
A cDNA encoding CYP79B1 has been isolated from Sinapis alba. CYP79B1 from S. alba shows 54% sequence identity and 73% similarity to sorghum CYP79A1 and 95% sequence identity to the Arabidopsis T42902, assigned CYP79B2. The high identity and similarity to sorghum CYP79A1, which catalyses the
One of the first steps in glucosinolate biosynthesis is the conversion of amino acids to their aldoximes. The biochemistry of this process is controversial, and several very different enzyme systems have been described. The major glucosinolate in white mustard (Sinapis alba) is sinalbin, which is
1. Lyase (L-Phenylalanine ammonia-lyase, EC 4.3.1.5) from far-red light-irradiated mustard cotyledons was purified to a single protein using ammonium sulphate fractionation, column chromatography on L-phenylalanyl-Sepharose 4B and on Sephadex G-200, isoelectric focusing and polyacryalmide gel
The antigenic sites on the major allergen from yellow mustard (Sinapis alba L.) seeds were studied using murine (BALB/c) monoclonal antibodies (mAb) and human IgE antibodies. Ten IgG1 (K) mAb from two fusions were analyzed. Competition and complementation studies performed with peroxidase labeled
