The properties of an RNA-dependent DNA polymerase (an RNA-dependent DNA nucleotidyltransferase), which occurs ubiquitously in the allantoic fluid of uninfected, leukosis-virus-free eggs, are described. It is shown that the enzyme can synthesize faithful transcripts from natural RNA (globin mRNA). By biochemical and immunological methods, the enzyme can be clearly distinguished from the reverse transcriptases of the known chicken RNA tumor viruses and therefore seems to be a member of a so far unknown class of chicken polymerases.
本文描述了一种依赖RNA的DNA聚合酶(一种依赖RNA的DNA核苷酸转移酶)的特性,该酶普遍存在于未感染、无白血病病毒的鸡蛋尿囊液中。研究表明,这种酶能够从天然RNA(珠蛋白mRNA)合成忠实的转录本。通过生化和免疫学方法,该酶能够与已知鸡RNA肿瘤病毒的逆转录酶明显区分开来,因此似乎属于一类迄今未知的鸡聚合酶。
