摘要: 本试验对伪狂犬病病毒SL株(四川分离株)TK基因进行克隆,并对TK基因的同源性、遗传进化树、密码子偏嗜性、氨基酸结构及亲疏水性、跨膜区、信号肽进行了分析。结果显示,本研究成功克隆了PRV SL株TK全基因,其编码区长963 bp,编码320个氨基酸残基,与其他PRV分离株核苷酸序列同源性超过99.3%,编码的多肽链中疏水区域大于亲水区域,不含跨膜区及信号肽,不存在于病毒囊膜。

Abstract: TK gene of pseudorabies virus SL strain was cloned. Based on the sequence, the homology, phylogeny tree, codon bias, amino acid structure, hydrophilic and hydrophobicity, transmembrane region and signal peptide were analyzed. The results showed that TK gene was successfully cloned and it consisted 963 nucleotides encoding a protein of 320 amino acids. The TK gene shared over 99.3% homology with that of the other PRV strains. PRV TK was predicted to not have the transmembrane region and signal peptide, and not be inside of virus envelope.

Key words: pseudorabies virus; TK gene; bioinformatics analysis
