Illuminating membrane fusion.
M embrane fusion is a central event for a wide variety of biological processes, such as transport of cargo through the secretory and endocytic pathways, organelle inheritance, neurotransmission, and viral entry into host cells, among others. Hence, understanding the mechanism(s) of physiological membrane fusion is a subject of wide biological interest, and extensive studies using theoretical an...
متن کاملX-ray crystallographic determination of the structure of the influenza C virus haemagglutinin-esterase-fusion glycoprotein.
The structure of the haemagglutinin-esterase-fusion (HEF) glycoprotein from influenza C virus has been determined to 3.2 A resolution by X-ray crystallography. A synthetic mercury-containing esterase inhibitor and receptor analogue, 9-acetamidosialic acid alpha-thiomethylmercuryglycoside, was designed as the single isomorphous heavy-atom derivative. The asymmetric unit of one crystal form (form...
متن کاملAnalyses of the antigenicity of influenza haemagglutinin at the pH optimum for virus-mediated membrane fusion.
At the pH optimum for membrane fusion the haemagglutinin glycoprotein (HA) of the influenza virus membrane which is implicated in the fusion activity undergoes a conformational change. We have analysed the effects of this change on the antigenicity of the haemagglutinin by reacting the molecule with monoclonal antibodies of defined specificity. The results obtained indicate that specific change...
متن کاملDirectionality in the evolution of influenza A haemagglutinin.
The evolution of haemagglutinin (HA), an important influenza virus antigen, has been the subject of intensive research for more than two decades. Many characteristics of HA's sequence evolution are captured by standard Markov chain substitution models. Such models assign equal fitness to all accessible amino acids at a site. We show, however, that such models strongly underestimate the number o...
متن کاملPathogenicity and haemagglutinin gene sequence analysis of Iranian avian influenza H9N2 viruses isolated during (1998–2001)
Sixteen avian influenza (AI) H9N2 viruses were isolated from disease outbreaks in different parts of Iranduring (1998–2001). These AI isolates were used for pathogenicity, haemagglutinin (HA) gene variation andphylogenetic analysis. Results in both pathogenicity tests and HA gene cleavage site sequence detectionrepresented a non-highly pathogenic feature for all Iranian AI isolates studied. The...
