this research tries to locate the protein interaction sites in conserved 9mer peptides (C9MP) between PB1 protein and PA protein in the nuclease complex of influenza A virus. There exist interaction regions between sites 1-15 amino acids of PB1 protein and sites 239-716 amino acids of PA protein from structure message. It is revealed by variation analysis to this region that
on PB1-MP1 contact surface
there is a minimum co-evolution value between the conserved 9mer peptide where Q670 of PA protein is located and the conserved 9mer peptide where F9
V12 and P13 of PB1 protein are located. Combined with DSSP analysis results
the regions formed by four amino acids
Q670 of PA protein
F9
V12 and P13 of PB1 protein
are potential interaction sites.
