T4 DNA拓扑异构酶是一种II型酶,被认为是T4 DNA正常复制所必需的。T4基因39编码T4 DNA拓扑异构酶三个亚基中最大的一个。我已经确定了T4 DNA的2568个核苷酸区域的核苷酸序列,该区域包括基因39。通过鉴定DNA序列中大的开放阅读框中的前15个氨基酸与在纯化的39-蛋白质的氨基末端发现的氨基酸相同,确定基因的位置。基因39的编码区有1560个碱基,其后是两个读框内终止密码子。该基因之前是一个典型的Shine-Dalgarno序列以及可能的E启动子序列。coliRNA聚合酶。T4 39-蛋白由520个氨基酸组成,其计算分子量为58,478。通过氨基酸序列比较,发现T4 39蛋白与DNA促旋酶的gyrB亚基具有同源性。这表明这些拓扑异构酶亚基在功能上可能是等同的。一些39-蛋白质的特点和它的结构特征预测的DNA序列数据进行了讨论。
T4 DNA topoisomerase is a type II enzyme and is thought to be required for normal T4 DNA replication T4 gene 39 codes for the largest of the three subunits of T4 DNA topoisomerase. I have determined the nucleotide sequence of a region of 2568 nucleotides of T4 DNA which includes gene 39. The location of the gene was established by the identification of the first fifteen amino acids in the large open reading frame in the DNA sequence as those found at the amino-terminus of the purified 39-protein. The coding region of gene 39 has 1560 bases, and it is followed by two in-frame stop codons. The gene is preceded by a typical Shine-Dalgarno sequence as well as possible promoter sequences forE. coliRNA polymerase. T4 39-protein consists of 520 amino acids, and it has a calculated molecular weight of 58, 478. By comparing the amino acid sequences, T4 39-protein is found to share homology with thegyrBsubunit of DNA gyrase. This suggests that these topoisomerase subunits may be equivalent functionally. Some of the characteristics of the 39-protein and its structural features predicted from the DNA sequence data are discussed.
