Dissection of a retrovirus envelope protein reveals structural similarity to influenza hemagglutinin


BACKGROUND The amino-acid sequences of retroviral envelope proteins contain a '4-3 hydrophobic repeat', with hydrophobic amino acids spaced every four and then every three residues, characteristic of sequences that form coiled coils. The 4-3 hydrophobic repeat is located in the transmembrane subunit (TM) of the retroviral envelope protein, adjacent to the… (More)
