Reticuloendotheliosis virus (REV) contains an endogenously instructed, RNA-directed DNA polymerase activity. Both the endogenous and exogenous DNA polymerase activities exhibited up to 10-fold greater activity at the optimum concentration of manganous ion (0.025 mM for exogenous; 0.25 mM for endogenous) than at any concentration of magnesium ion. Antiserum to the DNA polymerase of an REV group virus (spleen necrosis virus) inhibited both endogenous and exogenous DNA polymerase activity of REV, whereas antiserum to the Rous sarcoma virus (Rous-associated virus-0) [RSV(RAV-0)]DNA polymerase did not. The DNA product of the endogenous reaction is associated with the high-molecular-weight RNA of REV and anneals with REV RNA but not with RNA from Rous sarcoma virus.
网状内皮组织增殖病病毒(REV)含有一种内源性指导的、RNA 指导的 DNA 聚合酶活性。内源性和外源性 DNA 聚合酶活性在锰离子的最佳浓度(外源性为 0.025 mM;内源性为 0.25 mM)下表现出的活性比在任何镁离子浓度下高出多达 10 倍。针对 REV 组病毒(脾坏死病毒)的 DNA 聚合酶的抗血清抑制了 REV 的内源性和外源性 DNA 聚合酶活性,而针对劳氏肉瘤病毒(劳氏相关病毒-0)[RSV(RAV-0)]DNA 聚合酶的抗血清则没有。内源性反应的 DNA 产物与 REV 的高分子量 RNA 相关,并与 REV RNA 退火,但不与劳氏肉瘤病毒的 RNA 退火。
