Abstract
Purified recombinant protein encoded by the BXLF-I open reading frame of the Epstein-Barr virus genome has thymidine kinase activity. The substrate behaviors of various nucleosides toward this enzyme were tested. Halogenated deoxyuridines, zidovudine, and bromovinyldeoxyuridine are efficient substrates, while acyclovir and dihydroxypropylmethylguanine are relatively poor substrates for the Epstein-Barr virus thymidine kinase.
摘要
由爱泼斯坦-巴尔病毒基因组的BXLF-I开放阅读框编码的纯化重组蛋白具有胸苷激酶活性。测试了各种核苷对该酶的底物行为。卤代脱氧尿苷、齐多夫定和溴乙烯基脱氧尿苷是有效的底物，而阿昔洛韦和二羟丙基甲基鸟嘌呤是爱泼斯坦-巴尔病毒胸苷激酶相对较差的底物。
