La Crosse virus G1 glycoprotein undergoes a conformational change at the pH of fusion. 1985

F Gonzalez-Scarano

La Crosse virus, a member of the family Bunyaviridae, can mediate cell-to-cell fusion after mild acidification. Either of its two envelope glycoproteins could potentially be responsible for this function. The large glycoprotein (G1) undergoes a conformational change at the pH of activation of the fusion function, resulting in both an alteration in the cleavage pattern produced by amino-acid-specific proteases, and in a change in its antigenicity, as defined by altered binding of monoclonal antibodies.

D010455	Peptides	Members of the class of compounds composed of AMINO ACIDS joined together by peptide bonds between adjacent amino acids into linear, branched or cyclical structures. OLIGOPEPTIDES are composed of approximately 2-12 amino acids. Polypeptides are composed of approximately 13 or more amino acids. PROTEINS are considered to be larger versions of peptides that can form into complex structures such as ENZYMES and RECEPTORS.	Peptide,Polypeptide,Polypeptides
D011487	Protein Conformation	The characteristic 3-dimensional shape of a protein, including the secondary, supersecondary (motifs), tertiary (domains) and quaternary structure of the peptide chain. PROTEIN STRUCTURE, QUATERNARY describes the conformation assumed by multimeric proteins (aggregates of more than one polypeptide chain).
