INFLUENZA VIRUS MATRIX PROTEIN CRYSTAL STRUCTURE AT PH 4.0
OverviewOverview
Matrix protein (M1) of influenza virus is a bifunctional protein that, mediates the encapsidation of RNA-nucleoprotein cores into the membrane, envelope. It is therefore required that M1 binds both membrane and RNA, simultaneously. The X-ray crystal structure of the N-terminal portion of, type A influenza virus M1-amino acid residues 2-158-has been determined at, 2.08 A resolution at pH 4.0. The protein forms a dimer. A highly, positively charged region on the dimer surface is suitably positioned to, bind RNA while the hydrophobic surface opposite the RNA binding region may, be involved in interactions with the membrane. The membrane-binding, hydrophobic surface could be buried or exposed after a conformational, change.
