  1. 6. Structural and Functional Studies of Diiron Carboxylate Proteins

    Författare :Pål Stenmark; Pär Nordlund; Howard Dalton; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Biokemi;

    Sammanfattning : Iron is essential to all life; it is a vital component of many proteins in humans as well as plants and bacteria. Because of the ability of iron to activate oxygen, it is often found in proteins that interact with oxygen in some way. LÄS MER

  3. 7. Lipase-Catalyzed Syntheses of Telechelic Polyesters

    Författare :Magnus Eriksson; Karl Hult; Mats Martinelle; Sergio Riva; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Candida antarctica lipase B; lipase-catalysis; polymerization; telechelic; functional polyesters; ring-opening polymerization; polycondensation.; Biochemistry; Biokemi;

    Sammanfattning : Telechelic polyesters have successfully been synthesized with lipase-catalyzed polymerization. The produced telechelics had a high degree of di­functionalization, high purity (requiring little or no workup) and controlled degree of polymerization. The syntheses were performed in one-pot one-step reaction systems. LÄS MER

  4. 8. CPSRP54 and co-translational targeting of chloroplast encoded thylakoid membrane proteins

    Författare :Robert Nilsson; Ralph Henry; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : Chloroplasts are essential organelles of prokaryotic origin that are present in green tissue of higher plants and algae. Chloroplasts are predicted to contain ~3000 proteins and the vast majority of these proteins are encoded by nuclear genes. Chloroplasts also have a small circular genome encoding 100-120 tRNAs, rRNAs and proteins. LÄS MER

  5. 9. Directed mutagenesis and structure-function analyses of the psbA gene products, D1 and D1', in the cyanobacterium Synechosystis 6803

    Författare :Gaza Farag Salih; Lee McIntosh; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : Photosynthesis is the process by which the two essential requirements for man's survival on earth, food and oxygen, are produced. Oxygenic photosynthetic organisms, like plants, algae and the prokaryotic cyanobacteria, harness and convert the sunlight in specialized membranes called thylakoids. LÄS MER

  7. 10. Xyloglucan-active enzymes : properties, structures and applications

    Författare :Martin J. Baumann; Tuula T. Teeri; Harry Brumer; Vincent Eijsink; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; xyloglucan; xyloglucan endo-transglycosylase hydrolase; xyloglucan endo-hydrolase; xyloglucan endo-transglycosylase; XET; xyloglucan oligosaccharides; synthesis; carbohydrate; cellulose; crystal structure; fiber; surface modification; Populus tremula x Populus tremuloides; Hybrid aspen; nasturtium; NXG; Biochemistry; Biokemi;

    Sammanfattning : Cellulosabaserade material är världens rikligast förekommande förnyelsebara råvara. Växters cellväggar är naturliga kompositmaterial där den kristallina cellulosan är inbäddad i en väv av hemicellulosa, strukturproteiner och lignin. LÄS MER
