   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical library screening; Cell wall synthesis; Glycosylation; Nucleotide sugars; Oligomerization; Protein structure; Reverse chemical genetics; Sugar activation; UDP-sugar synthesis; biokemisk farmakologi; biochemical pharmacology; biokemi; Biochemistry; biology; biologi; molekylärbiologi; Molecular Biology;

   Abstract : UDP-sugar metabolizing pyrophosphorylases provide the primary mechanism for de novo synthesis of UDP-sugars, which can then be used for myriads of glycosyltranferase reactions, producing cell wall carbohydrates, sucrose, glycoproteins and glycolipids, as well as many other glycosylated compounds. The pyrophosphorylases can be divided into three families: UDP-Glc pyrophosphorylase (UGPase), UDP-sugar pyrophosphorylase (USPase) and UDP-N-acety lglucosamine pyrophosphorylase (UAGPase), which can be discriminated both by differences in accepted substrate range and amino acid sequences.

4. 2. Studies on the Role of UDP-Glucose Dehydrogenase in Polysaccharide Biosynthesis

   Author : Elisabet Roman; Marion Kusche-Gullberg; Hakon Leffler; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; UDP-glucose dehydrogenase; polysaccharide biosynthesis; glycosaminoglycan; A. thaliana; E. coli K5; Biokemi; Biochemistry; Biokemi; Medical and Physiological Chemistry; medicinsk och fysiologisk kemi;

   Abstract : Polysaccharides are found in all forms of life and serve diverse purposes. They are enzymatically synthesised from activated monosaccharide precursors, nucleotide sugars. One such nucleotide sugar is UDP-glucuronic acid, which is formed from UDP-glucose by the UDP-glucose dehydrogenase (UGDH) enzyme. READ MORE

   Abstract : Glucosamine (GlcN) and glucosamine sulfate (GS) have been used to treat the patients with osteoarthritis(OA) as a disease-modifying agent. Previousin vitro studies have focused on the effects of GlcN or GSon cartilage metabolism, whereas in vivo studies have investigated their potential for the treatment of OA. READ MORE
