Table 1 Key amino-acid changes in the full genome of JX14737 virus isolated from air samples

From: Avian influenza H9N2 virus isolated from air samples in LPMs in Jiangxi, China

Protein Amino-Acid Mutations Phenotype
PB2 292 V Increases polymerase activity in 293 T cells
588 V Enhanced polymerase activity and viral replication in human NHBE cells
HA Q226La Increased viral binding to α2,6-sialic acid receptor, airborne transmission between mammals
N/K137Aa Avian-like receptor binding preference (N/137 K)
  1. aThe amino acid positions of HA gene represent H3 numbering
