BIOTECHNOLOGICALLY RELEVANT ENZYMES AND PROTEINS Expression of chondroitin-4-O-sulfotransferase inEscherichia coli and Pichia pastoris
Chondroitin sulfates are linear sulfated polysaccharides called glycosaminoglycans. They are important nutraceutical and pharmaceutical products that are biosynthesized through the action of chondroitin sulfotransferases on either an unsulfated chondroitin or a dermatan polysaccharide precursor. While the enzymes involved in the biosynthesis of chondroitin sulfates are well known, the cloning e...
متن کاملA mutant Escherichia coli that attaches peptidoglycan to lipopolysaccharide and displays cell wall on its surface
The lipopolysaccharide (LPS) forms the surface-exposed leaflet of the outer membrane (OM) of Gram-negative bacteria, an organelle that shields the underlying peptidoglycan (PG) cell wall. Both LPS and PG are essential cell envelope components that are synthesized independently and assembled by dedicated transenvelope multiprotein complexes. We have identified a point-mutation in the gene for O-...
متن کاملCytoplasmic steps of peptidoglycan synthesis in Escherichia coli.
The cellular pool levels of most of the cytoplasmic precursors of peptidoglycan synthesis were determined for normally growing cells of Escherichia coli K-12. In particular, a convenient method for analyzing the uridine nucleotide precursor contents was developed by associating gel filtration and reverse-phase high-pressure liquid chromatography techniques. The enzymatic parameters of the four ...
متن کاملModified peptidoglycan chemical composition in shape-altered Escherichia coli.
Peptidoglycan synthesis and its fine chemical composition were studied in dividing cocci of Escherichia coli carrying the lov-1 mutation and in which the coccal shape was obtained either by mecillinam treatment or by transferring a pbpA mutation (penicillin-binding protein 2- phenotype), as compared to normal rods and non-dividing cocci. Synchronously dividing cocci showed peptidoglycan synthes...
متن کاملDensity and Temperature Dependencies of Liquid Surface Tension
In this paper the density and temperature dependencies of surface tension are investigated. Using the Lennard-Jones (12,6), as an effective pair interaction potential, a linear expression is derived for isotherms of g /r2 versus r2 for some normal and ChloroFluoroCarbons (CFCs)</...
