Journal ArticleDOI
Detoxification of the Fusarium Mycotoxin Deoxynivalenol by a UDP-glucosyltransferase from Arabidopsis thaliana
Brigitte Poppenberger,Franz Berthiller,Doris Lucyshyn,Tobias Sieberer,Rainer Schuhmacher,Rudolf Krska,Karl Kuchler,Josef Glössl,Christian Luschnig,Gerhard Adam +9 more
TL;DR: The isolation and characterization of a gene from Arabidopsis thaliana encoding a UDP-glycosyltransferase that is able to detoxify deoxynivalenol is reported, and it is shown that this enzymatic reaction inactivates the mycotoxin.
Journal ArticleDOI
Glycosyltransferases: managers of small molecules
TL;DR: Glycosylation alters the hydrophilicity of the acceptors, their stability and chemical properties, their subcellular localisation and often their bioactivity, and the utility of GTs as biocatalysts is understood.
Journal ArticleDOI
Glycosyltransferases of lipophilic small molecules.
TL;DR: The role of these glycosyltransferases in underpinning developmental and metabolic plasticity during adaptive responses is discussed, which suggests that in a cellular context, substrate availability is a determining factor in enzyme function, and redundancy depends on the extent of coordinate gene regulation.
Journal ArticleDOI
Toxin–antitoxin systems: Biology, identification, and application
TL;DR: Toxin–antitoxin systems are small genetic elements composed of a toxin gene and its cognate antitoxin and their potential to combat viral infection may aid in controlling infectious diseases.
Journal ArticleDOI
The UGT73C5 of Arabidopsis thaliana glucosylates brassinosteroids
Brigitte Poppenberger,Shozo Fujioka,Kazuo Soeno,Gilu George,Fabián E. Vaistij,Sayoko Hiranuma,Hideharu Seto,Suguru Takatsuto,Gerhard Adam,Shigeo Yoshida,Dianna J. Bowles +10 more
TL;DR: The hypothesis that 23-O-glucosylation of BL is a function of UGT73C5 in planta, and that glucosylations regulates BR activity is supported, is supported.
