Sinapoylglucose: Malate Sinapoyltransferase Activity in Arabidopsis thaliana and Brassica rapa
نویسندگان
چکیده
Protein preparations from Arabidopsis thaliana and Brassica rapa catalyzed the formation o f O-sinapoyl-L-malate using 1-O-sinapoyl-ß-glucose as acyl donor. The enzyme involved, 1-O-sinapoyl-ß-glucose :L-malate O-sinapoyltransferase (SMT; EC 2 .3 .1 .-) , catalyzes in the cotyledons o f the seedlings the key step in the conversion o f the seed constituent sinapine (O-sinapoylcholine) to sinapoylmalate by way o f the intermediate sinapoylglucose.

Related Arabidopsis serine carboxypeptidase-like sinapoylglucose acyltransferases display distinct but overlapping substrate specificities.
The Arabidopsis (Arabidopsis thaliana) genome encodes 51 proteins annotated as serine carboxypeptidase-like (SCPL) enzymes. Nineteen of these SCPL proteins are highly similar to one another, and represent a clade that appears to be unique to plants. Two of the most divergent proteins within this group have been characterized to date, sinapoyl-glucose (Glc):malate sinapoyltransferase and sinapoy...
متن کاملSinapic acid ester metabolism in wild type and a sinapoylglucose-accumulating mutant of arabidopsis.
Sinapoylmalate is one of the major phenylpropanoid metabolites that is accumulated in the vegetative tissue of Arabidopsis thaliana. A thin-layer chromatography-based mutant screen identified two allelic mutant lines that accumulated sinapoylglucose in their leaves in place of sinapoylmalate. Both mutations were found to be recessive and segregated as single Mendelian genes. These mutants defin...
متن کاملAn expression and bioinformatics analysis of the Arabidopsis serine carboxypeptidase-like gene family.
The Arabidopsis (Arabidopsis thaliana) genome encodes a family of 51 proteins that are homologous to known serine carboxypeptidases. Based on their sequences, these serine carboxypeptidase-like (SCPL) proteins can be divided into several major clades. The first group consists of 21 proteins which, despite the function implied by their annotation, includes two that have been shown to function as...
متن کاملProgress in Understanding and Sequencing the Genome of Brassica rapa
Brassica rapa, which is closely related to Arabidopsis thaliana, is an important crop and a model plant for studying genome evolution via polyploidization. We report the current understanding of the genome structure of B. rapa and efforts for the whole-genome sequencing of the species. The tribe Brassicaceae, which comprises ca. 240 species, descended from a common hexaploid ancestor with a bas...
متن کاملGenetic engineering of Arabidopsis to overproduce disinapoyl esters, potential lignin modification molecules
BACKGROUND Monolignol-like molecules can be integrated into lignin along with conventional monolignol units, and it has been shown that the incorporation of non-canonical subunits can be used to generate hydrolysable lignin by introduction of ester linkages into the polymer and that this type of lignin is more easily removable. Disinapoyl esters (DSEs), which to some degree resemble the monolig...
