Abstract
Present invention discloses the three-dimensional crystal structure of the N-terminus polypeptide of influenza virus polymerase subunit (PA_N of SEQ ID NO:7). PA_N of SEQ ID NO: 1 is residues 1—50 to 150-300 of influenza virus polymerase subunit PA. In the three-dimensional structure, at least 40% of atoms show the same atomic coordinates, compared to that listed in Table 1. Namely, in the three-dimensional structure of influenza virus polymerase subunit PA_N of SEQ ID NO: 7, 40% of atomic coordinates on carbon skeleton of residues of influenza virus polymerase subunit PA_N of SEQ ID NO: 7, show less than or equal to 1.7 Å of average variance, compared to the atomic coordinates listed in Table 1. Present invention also discloses the expression, purification, crystallization methods, and three-dimensional crystal structure of 256 residues in the N-terminus of influenza virus polymerase subunit PA, and applications of the crystal structure of SEQ ID NO: 7 on drug screening and designing.
