  1. 6. Ferrochelatase and Magnesiumchelatase: Metal chelation studied with mutants

    Författare :Ulf Olsson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; chlorophyll; heme; barley; mutants; Magnesium chelatase; ferrochelatase; Metabolism; Biokemi; metabolism;

    Sammanfattning : Magnesium chelatase and ferrochelatase are two very important enzymes, which are involved in chlorophyll and heme biosynthesis, respectively. They both use protoporphyrin IX as substrate but magnesium chelatase inserts a magnesium ion whereas ferrochelatase inserts a ferrous ion. These two enzymes have been studied in this thesis. LÄS MER

  3. 7. Enzymatic metal-chelation by porphyrins

    Författare :Andreas Hansson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tetrapyrrole; Plant biochemistry; Växtbiokemi; MIDAS; metallation; magnesium chelatase; integrin; heme; ferrochelatase; chlorophyll; barley; AAA ; ATPase;

    Sammanfattning : This thesis deals with the structure and function of two different enzymes, ferrochelatase and magnesium chelatase, that catalyse similar reactions. When this work started, a three-dimensional model of ferrochelatase existed. Much was known about the enzyme, but some details remained unclear. LÄS MER
