  1. 1. Human intestinal alkaline phosphatase : tissue expression and serum levels

    Författare :Ulla Domar; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Human alkaline phosphatase; intestinal alkaline phosphatase; blood; blood group; lipid; monoclonal antibody; immunohistochemistry; liver; kidney; pancreas; liver disease; inflammatory bowel disease;

    Sammanfattning : Human alkaline phosphatase (ALP) comprises four isozymes, viz liver/bone/ kidney or tissue unspecific (AP), intestinal (LAP), placental (PLAP) and germ cell or PLAP-like alkaline phosphatase, with their main expression in specific tissues as indicated by their names. The isozymes are coded by different genes, but they are closely related, with more than 50% amino acid sequence homologies. LÄS MER

  3. 2. Studies on Phosphohistidine Phosphatase 1 : What? Where? Why?

    Författare :Ulla Beckman Sundh; Pia Ek; Örjan Zetterqvist; Jin-ping Li; Christian Hedberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PHPT1; Phosphohistidine phosphatase; PHP; Assay; Medical Biochemistry; Medicinsk biokemi;

    Sammanfattning : Phosphohistidine phosphatase 1 (PHPT1) is a small protein, consisting of 125 amino acids, that catalyzes the dephosphorylation of histidine but does not have any activity towards other phosphorylated amino acids. PHPT1 was identified in 2002, and is so far the only mammalian histidine phosphatase known, but still little is known about its physiological role. LÄS MER

  4. 3. Promiscuity and Selectivity in Phosphoryl Transferases

    Författare :Alexandre Barrozo; Shina Kamerlin; Qiang Cui; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phosphate chemistry; linear free energy relationships; phosphatase; catalytic promiscuity; empirical valence bond approach; alkaline phosphatase;

    Sammanfattning : Phosphoryl transfers are essential chemical reactions in key life processes, including energy production, signal transduction and protein synthesis. They are known for having extremely low reaction rates in aqueous solution, reaching the scale of millions of years. LÄS MER

  5. 4. The Ecophysiology of Arbuscular Mycorrhizal Fungi: Phosphatase Activity Associated with Extraradical and Intraradical Mycelium

    Författare :Ingrid van Aarle; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ekologi; Ecology; mykologi; virologi; bakteriologi; Mikrobiologi; mycology; virology; bacteriology; Microbiology; Scutellospora; polyphosphate; phosphorus uptake; phosphorus transfer; phosphatase; pH; mycelium; Glomus; fatty acid; Gigaspora; arbuscular mycorrhiza; ELF;

    Sammanfattning : Arbuscular mycorrhizal (AM) fungi colonise a wide range of plant species and are especially common in soils with a relatively high pH, where phosphorus availability is a limiting factor for primary production. The aim of this thesis was to study the ecophysiology of arbuscular mycorrhizal (AM) fungi when exposed to different environments. LÄS MER
