   Sammanfattning : 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.

3. 17. Insights into potato plant immunity reveals Parakletos as a novel ROS suppressor

   Författare :Muhammad Awais Zahid; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : Potato (Solanum tuberosum L.) is the world's third most commonly grown food crop with very high yield potential. However, its production is hampered by several pathogens, with consequent yield losses. Existing control methods include frequent, costly fungicide applications, and classical breeding is complicated in potato. LÄS MER

4. 18. Plant UDP-glucose Pyrophosphorylase : Function and Regulation

   Författare :Meng Meng; Leszek Kleczkowski; Javier Pozueta-Romero; Umeå universitet; []

   Sammanfattning : Enzymes are extraordinary molecules that can accelerate chemical reactions by several orders of magnitude. With recent advancements in structural biology together with classical enzymology the mechanism of many enzymes has become understood at the molecular level. LÄS MER

7. 20. Phytoglobins: Elucidation of Structural, Functional and Practical Features of Non-Symbiotic Plant Hemoglobins

   Författare :Simon Christensen; Tillämpad biokemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hemoglobin; Fytoglobin; Hexakoordination; Karaktärisering; Protein design; Rekombinant protein production; Kromatografi; kristallografi; Dimerisering; Protein Dynamik;

   Sammanfattning : Phytoglobins (Pgb) (plant hemoglobins) are heme-containing proteins and less well known in comparison to the mammalian counterparts hemoglobin (Hb) andmyoglobin (Mb). They share the same secondary structure as other globin-related proteins, six to eight α-helices comprising the myoglobin-fold (Mb-fold) with one prosthetic heme moiety per subunit. LÄS MER
