Details | THERE IS ONE MONOMER OF THE TRIMERIC HEMAGGLUTININ MOLECULE IN THE ASYMMETRIC UNIT, AND EACH MONOMER IS COMPLEXED WITH ONE FAB FRAGMENT. THE MONOMER OF HEMAGGLUTININ CONSISTS OF TWO CHAINS, IDENTIFIED AS HA1 AND HA2. CHAINS HA1 AND HA2 HAVE BEEN ASSIGNED CHAIN IDENTIFIERS *A* AND *B*, RESPECTIVELY. IN THE VIRUS, CHAIN HA1 CONSISTS OF 328 RESIDUES AND CHAIN HA2 CONSISTS OF 220 RESIDUES. HEMAGGLUTININ MAY BE SOLUBILIZED FROM THE VIRAL MEMBRANE BY BROMELAIN DIGESTION, WHICH REMOVES THE C-TERMINAL HYDROPHOBIC (ANCHORING) DOMAIN FROM CHAIN HA2. AFTER BROMELAIN DIGESTION CHAIN HA2 CONSISTS OF 175 RESIDUES, AS PRESENTED IN THIS ENTRY. |
