Comparative surface feature analyses of the VP1 sequences of hepatitis A virus (HAV) and poliovirus type 1 allowed an alignment of the two sequences and an identification of probable HAV neutralization antigenic sites. A synthetic peptide containing the HAV-specific amino acid sequence of one of these sites induced anti-HAV-neutralizing antibodies. It is concluded that a structural homology exists between the two viruses, despite minimal primary sequence conservation.
对甲型肝炎病毒(HAV)和1型脊髓灰质炎病毒的VP1序列进行比较表面特征分析,使得这两个序列得以比对,并确定了可能的HAV中和抗原位点。包含其中一个位点的HAV特异性氨基酸序列的合成肽可诱导抗HAV中和抗体。得出的结论是,尽管一级序列保守性极低,但这两种病毒之间存在结构同源性。
