alpha glucosidase/arabidopsis thaliana

N-glycosylation is a common protein modification. Joining of polypeptide and carbohydrate elements into hybrid molecules provides an opportunity to fine-tune protein properties. However, the role of N-glycosylation on the development of multicellular organisms remains elusive. Here we report a

Two alpha-glucosidase inhibitors were isolated from the flowers of Sesbania grandiflora and named SGF60 and SGF90. The procedure involved extraction with phosphate buffer, precipitation with ammonium sulfate, ion-exchange chromatography on DEAE-cellulose and gel filtration on Superdex-200. These

Using an Arabidopsis thaliana expressed sequence tag with sequence similarity to human lysosomal alpha-glucosidase as a probe, a potato cDNA was isolated. The cDNA encodes a polypeptide with an Mr value of 105,400 and the most significant matches of the deduced amino acid sequence are with members

Assembly of the dolichol-linked oligosaccharide precursor (Glc(3) Man(9) GlcNAc(2) ) is highly conserved among eukaryotes. In contrast to yeast and mammals, little is known about the biosynthesis of dolichol-linked oligosaccharides and the transfer to asparagine residues of nascent polypeptides in

Small molecule modulators of the Endoplasmic Reticulum glycoprotein folding quality control (ERQC) machinery have broad-spectrum antiviral activity against a number of enveloped viruses and have the potential to rescue secretion of misfolded but active glycoproteins in rare diseases. In vivo assays

We report the isolation, sequencing and analysis of the cDNA corresponding to an alpha-D-xylosidase involved in the mobilisation of xyloglucan from the cotyledons of germinated nasturtium (Tropaeolum majus L.) seeds. The translated open reading frame (2,808 bp including the stop codon), gave a

With nearly 140 α-glycosidases in 14 different families, plants are well equipped with enzymes that can break the α-glucosidic bonds in a large diversity of molecules. Here, we introduce activity-based protein profiling (ABPP) of α-glycosidases in plants using α-configured cyclophellitol aziridine
