摘要
丙型肝炎病毒(HCV)非结构蛋白NS3共有631个氨基酸组成,具有丝氨酸蛋白酶、三磷酸核苷酶(NTpase)和螺旋酶(Helicase)的功能,在HCV多聚蛋白的成熟和病毒复制过程中发挥着重要作用.非结构蛋白NS4A,其主要功能就是作为NS3丝氨酸蛋白酶的辅助因子,在HCV多氨酸成熟过程中发挥着不可替代的调节作用.此外,NS3/4A还参与NS5A的超磷酸化修饰过程.
Hepatitis C virus(HCV) nonstructural protein NS3 is composed of 631 amino acids, has the functions of serine protease, NTPase and helicase, which are essential for the development of HCV polyprotein maturation and HCV replication. HCV nonstructural protein NS4A, as NS3 serine protease cofactor, plays an irreplaceable regulating role during the development of HCV polyacids maturation.
