  1. 21. Structural / functional studies on human alkaline phosphatases

    Författare :Alexey Kozlenkov; Jose-Luis Millan; Hans Jörnvall; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomedicine; mutagenesis; enzyme kinetics; computer modeling; crystallography; natural substrates; uncompetitive inhibition; isozymes; gene families; Biomedicin; Microbiology; Mikrobiologi; medicinsk genetik; Medical Genetics;

    Sammanfattning : The recent elucidation of the three-dimensional structure of human placental alkaline phosphatase (PLAP) has enabled me to perform structural studies aimed at characterizing the properties of human PLAP and tissue-nonspecific AP (TNAP) as paradigms for mammalian APs in general, using site-directed mutagenesis, protein expression, kinetic analysis and computer modeling. In Paper I, we found that a single critical E429G substitution explains the difference in stability and kinetics between the common allelic variants of PLAP and the D allozyme. LÄS MER

  3. 22. Metal distribution and mobility under alkaline conditions

    Författare :Mårten Dario; Bert Allard; Yngve Albinsson; Örebro universitet; []

    Sammanfattning : The adsorption of an element, expressed as its distribution between liquid (aquatic) and solid phases in the biogeosphere, largely determines its mobility and transport properties. This is of fundamental importance in the assessment of the performance of e.g. geologic repositories for hazardous elements like radionuclides. LÄS MER
