  2. 1. Enzymatic metal-chelation by porphyrins

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

    Abstract : 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. READ MORE
