The complete nucleotide sequence of the hemagglutinin gene of influenza virus A/USSR/90/77 was determined. Comparison of hemagglutinin amino acid sequences from H1 field strains revealed five potential antigenic sites. Four of these sites correspond to those observed for H3 hemagglutinins, whereas the fifth apparently derives from differences in the glycosylation patterns between subtypes.
测定了甲型流感病毒A/USSR/90/77血凝素基因的完整核苷酸序列。对H1田间毒株血凝素氨基酸序列的比较揭示了五个潜在的抗原位点。其中四个位点与H3血凝素中观察到的位点相对应,而第五个位点显然源于亚型间糖基化模式的差异。
