single-stranded dna viruses 中文意思是什麼
single-stranded dna viruses
解釋
單鏈dna病毒-
The orf1 proteins of all four chinese senv isolates had two motifs ( ftl and yxxk ) which were conserved in replication - associated proteins. in all four chinese senv isolates, the putative non - structure orf2 protein had a cav - like region. the putative orf3 protein had a serine - rich tract preceded by a cluster of basic amino acids ( r and k ). database scaning suggested this region had high a percentage of homology with dna topoisomerase i protein of d. melanogaster, and might play an important role in the replication of such single - stranded dna viruses
所有這四個中國分離株，均保留了o即1中與復制有關的保守序列（ ftl和yxxk ） :在推測是非結構蛋白的orfz中均含有cav樣保守區w 『 x7一h一x3一c一xl一c一xs一h ; orf3蛋白的堿性氨基酸（精氨酸和賴氨酸）簇后緊接著一個富含絲氨酸的區域，與d . molanogaster的dna拓撲異構酶i有一定的同源性，推測在單鏈dna的復制中起作用。
