Populations of transfer ribonucleic acid (tRNA) extracted from control and type 2 adenovirus (Ad2)-infected KB cells were compared. No consistent differences in acceptor activity for 11 amino acids were observed. Comparison of methylated albumin-kieselguhr (MAK) elution profiles of arginyl-tRNA from control and infected cells revealed a minor modification in that the proportion of arginyl-tRNA eluting at high salt concentration was somewhat greater in infected cells. No similar differences were observed in MAK elution profiles of aspartyl-, isoleucyl-, leucyl-, phenylalanyl-, seryl-, tyrosyl-, and valyl-tRNA. Hybridization of 4S RNA from infected cells labeled by incorporation of (3)H-uridine with Ad2 deoxyribonucleic acid revealed the presence of a complementary species of RNA in this preparation. Hybridization of (3)H-arginyl-tRNA and of (3)H-aminoacyl-tRNA labeled by charging with (3)H-arginine or a (3)H-mixture of amino acids, respectively, failed to detect the presence of virus-specific tRNA in Ad2-infected cells.
对从对照细胞和2型腺病毒(Ad2)感染的KB细胞中提取的转移核糖核酸(tRNA)群体进行了比较。未观察到11种氨基酸的受体活性存在一致差异。对对照细胞和感染细胞中精氨酰-tRNA的甲基化白蛋白-硅藻土(MAK)洗脱图谱进行比较,发现有微小改变,即感染细胞中在高盐浓度下洗脱的精氨酰-tRNA比例略高。天冬氨酰-tRNA、异亮氨酰-tRNA、亮氨酰-tRNA、苯丙氨酰-tRNA、丝氨酰-tRNA、酪氨酰-tRNA和缬氨酰-tRNA的MAK洗脱图谱未观察到类似差异。用(3)H-尿苷掺入法标记的感染细胞的4S RNA与Ad2脱氧核糖核酸杂交,结果显示该制剂中存在一种互补RNA。分别用(3)H-精氨酸或(3)H-氨基酸混合物进行电荷标记的(3)H-精氨酰-tRNA和(3)H-氨酰-tRNA杂交,未能检测到Ad2感染细胞中存在病毒特异性tRNA。
