  1. 1. Insights into structure and dynamics of the AAA+ motor of magnesium chelatase

    Författare :Joakim Lundqvist; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bioinformatik; biomathematics biometrics; Bioinformatics; medical informatics; Rhodobacter capsulatus; Tetrapyrrole; Mutants; Magnesium chelatase; Cryo-Electron microscopy single-particle 3D reconstruction; Chlorophyll biosynthesis; AAA proteins; ATPase; medicinsk informatik; biomatematik; Molecular biophysics; Molekylär biofysik; Natural science; Naturvetenskap;

    Sammanfattning : The insertion of Mg2+ into protoporphyrin IX represents the first committed step in the chlorophyll and bacteriochlorophyll biosynthetic pathways. The reaction is catalyzed by the multisubunit enzyme Mg-chelatase, which consists of three subunits, known as I (molecular weight ~40 kDa), D (~70 kDa), and H (~140 kDa). LÄS MER
