Inhibition of the ribonucleic acid (RNA)- and deoxyribonucleic acid (DNA)-dependent DNA polymerase activities of mammalian C-type viruses was obtained with sera from rats bearing murine leukemia virus-induced transplant tumors. Polymerase activities of nonmammalian (viper) C-type virus and murine mammary tumor virus were not inhibited by such sera nor by serum from a rat immunized with the DNA polymerase of feline leukemia virus purified by isoelectric focusing. The latter serum appeared to inhibit preferentially the DNA-dependent DNA polymerase activity of mammalian C-type viruses showing no inhibition of RNA-dependent DNA synthesis.
携带鼠白血病病毒诱导的移植肿瘤的大鼠血清可抑制哺乳动物C型病毒的核糖核酸(RNA)依赖性和脱氧核糖核酸(DNA)依赖性DNA聚合酶活性。非哺乳动物(蝰蛇)C型病毒和鼠乳腺肿瘤病毒的聚合酶活性不受此类血清抑制,用等电聚焦法纯化的猫白血病病毒DNA聚合酶免疫的大鼠血清也不能抑制其活性。后一种血清似乎优先抑制哺乳动物C型病毒的DNA依赖性DNA聚合酶活性,而对RNA依赖性DNA合成没有抑制作用。
