The comparative analysis of sequences indicated that the sequences of meq in different pathotypes are relatively conserved and the homology of the amino acid sequences is very high . the significant differences include two mutations in both mdv - 1 vaccine strains cvi988 / rispens and 814 strain : the deletion of a proline ( no . l93aa ) , and this mutation is just exactly located in a 15 - amino - acid ( eelcaqlcstppppi ) repeat sequence within the c - terminal transactivation domain of meq protein ; and a point mutation with a shift from alanine ( a ) of all virulent strains to serine ( s ) was occurred on the no . 71 aa 結果發現, mdv不同致病型的meq基因序列相對比較保守,它們相互間核苷酸和氨基酸序列的同源性均很高;但是,與所有七個致瘤性的mdv毒株相比,二個型弱毒疫苗cv1988 rispens株和814株均出現了兩個特征性的突變:即第194位的p缺失性突變和第71位氨基酸由a變成了s的位點突變;缺失性突變恰恰位于meq基因中轉錄激活域內的一個多脯氨酸的重復序列( pppp )之中。 |
