  • Title: The coordination and function of the redox centres of the membrane-bound nitrate reductases.
    Author: Blasco F, Guigliarelli B, Magalon A, Asso M, Giordano G, Rothery RA.
    Journal: Cell Mol Life Sci; 2001 Feb; 58(2):179-93. PubMed ID: 11289300.
    Abstract:
    Under anaerobic conditions and in the presence of nitrate, the facultative anaerobe Escherichia coli synthesises an electron-transport chain comprising a primary dehydrogenase and the terminal membrane-bound nitrate reductase A (NarGHI). This review focuses on recent advances obtained on the structure and function of the three protein subunits of membrane-bound nitrate reductases. We discuss a global architecture for the Mo-bisMGD-containing subunit (NarG) and a coordination model for the four [Fe-S] centres of the electron-transfer subunit (NarH) and for the two b-type haems of the anchor subunit NarI.
