随着分子生物学的发展,从前通过免疫化学、血清学或简单的生物物理学方法描述的寄生虫蛋白质现在可通过cDNA克隆和核苷酸序列分析以及一级结构的推断作出新的定义。在一些情况下,若寄生虫蛋白与另一种已知功能的蛋白的氨基酸顺序具有同源 With the development of molecular biology, parasitic proteins previously described by immunochemical, serological or simple biophysical methods can now be defined by cDNA cloning and nucleotide sequence analysis as well as the primary structure inference. In some cases, if the parasite protein is homologous to the amino acid sequence of another protein of known function
