Identification of a Fragment-Based Scaffold that Inhibits the Glycosyltransferase WaaG from Escherichia coli "2279
WaaG is a glycosyltransferase that is involved in the biosynthesis of lipopolysaccharide in Gram-negative bacteria. Inhibitors of WaaG are highly sought after as they could be used to inhibit the biosynthesis of the core region of lipopolysaccharide, which would improve the uptake of antibiotics. Herein, we establish an activity assay for WaaG using 14C-labeled UDP-glucose and LPS purified from...
متن کاملMutation of the lipopolysaccharide core glycosyltransferase encoded by waaG destabilizes the outer membrane of Escherichia coli by interfering with core phosphorylation.
In Escherichia coli, phosphoryl substituents in the lipopolysaccharide core region are essential for outer membrane stability. Mutation of the core glucosyltransferase encoded by waaG (formerly rfaG) resulted in lipopolysaccharide truncated immediately after the inner core heptose residues, which serve as the sites for phosphorylation. Surprisingly, mutation of waaG also destabilized the outer ...

High-yield expression and purification of a monotopic membrane glycosyltransferase.
Membrane proteins are essential to many cellular processes. However, the systematic study of membrane protein structure has been hindered by the difficulty in obtaining large quantities of these proteins. Protein overexpression using Escherichia coli is commonly used to produce large quantities of protein, but usually yields very little membrane protein. Furthermore, optimization of the express...
متن کاملMembrane interactions of glycosyltransferases
Many important biological processes occur near or in membranes. The role of membranes is not merely confined to compartmentalization, they also form the matrix for membrane associated proteins and are of functional importance. Membrane associated proteins on the other hand require specific membrane properties for proper function. The interactions between membranes and proteins are thus of param...
