Metabolism of conjugated sterols in eggplant. Part 2. Phospholipid : steryl glucoside acyltransferase.
A membrane-bound phospholipid : steryl glucoside acyltransferase from Solanum melongena leaves was partially purified and its specificity and molecular as well as kinetic properties were defined. Among the steryl glycosides tested (e.g. typical plant steryl glucosides, steryl galactosides and cholesteryl xyloside) the highest activity was found with cholesteryl glucoside, but some structurally ...
متن کاملBrassinolide-2,3-acetonide: a brassinolide-induced rice lamina joint inclination antagonist.
A novel chemical tool compound that is an antagonist of brassinolide (BL, 1)-induced rice lamina joint inclination was developed. Although 2-O-, 3-O-, 22-O-, or 23-O-methylation of BL causes a critical decrease in biological activity,(5) a crystal structure of the extracellular leucine-rich repeat (LRR) domain of BRASSINOSTEROID-INSENSITIVE I (BRI1) bound to BL(3,4) indicates that the loss of a...
متن کاملProperties of pyridoxine glucoside.
Intact pyridoxine glucoside showed about 20% of microbiological activity of equivalent mole of pyridoxine for Saccharomyces carlsbergensis 4228 ATCC 9080. The activity was gradually increased accompanied with the prolonged incubation. It seems that pyridoxine glucoside is hydrolyzed to pyridoxine and glucose by a-glucosidase of Saccharomyces carlsbergensis 4228 ATCC 9080 and can be bioassayed a...
متن کاملThe plasma lecithins:cholesterol acyltransferase reaction.
Evidence for the existence of a plasma lecithin : cholesterol acyltransferase is reviewed with emphasis not only on the lipid reactants, but also on the lipoprotein "substrates" and "products." The cholesteryl esters of all major lipoprotein classes become labeled when plasma is incubated with cholesterol-(14)C. However, the smaller, lecithin-rich high density lipoproteins appear to be preferre...
متن کاملThe BRI1-Associated Kinase 1, BAK1, Has a Brassinolide-Independent Role in Plant Cell-Death Control
Programmed cell death (PCD) is a common host response to microbial infection [1-3]. In plants, PCD is associated with immunity to biotrophic pathogens, but it can also promote disease upon infection by necrotrophic pathogens [4]. Therefore, plant cell-suicide programs must be strictly controlled. Here we demonstrate that the Arabidopsis thaliana Brassinosteroid Insensitive 1 (BRI1)-associated r...
