  • Title: Recognition of receptor lipopolysaccharides by spike G protein of bacteriophage phiX174.
    Author: Kawaura T, Inagaki M, Karita S, Kato M, Nishikawa S, Kashimura N.
    Journal: Biosci Biotechnol Biochem; 2000 Sep; 64(9):1993-7. PubMed ID: 11055411.
    Abstract:
    The spike G protein of bacteriophage phiX174 was prepared as a hexa histidine-tagged G protein (HisG). In the enzyme-linked plate assay, HisG bound specifically to lipopolysaccharides (LPSs) of the phiX174-sensitive strains, and did not bind to LPSs of the phiX174-insensitive strains. The truncated G protein obtained after trypsin digestion of HisG had the similar affinity to the LPSs to HisG, indicating that eight amino acid residues from the N-terminus are not essential to the binding with the LPSs.
