Abstract
Gartner, Theodore K. (University of California, Davis), and Monica Riley. Genetic analysis of tryptophanase mutants of Escherichia coli. J. Bacteriol. 89:319-325. 1965.-The tryptophanase structural gene tna, and one of the tryptophanase regulation genes, R(1)tna, are closely linked, and lie between the pyr-E and ilv genes on the Escherichia coli chromosome. The mutant form of the regulation gene, which confers the properties of inducibility at 13 C, constitutivity at 37 C, and hyperinducibility at 37 C, is dominant over the wild form of the gene. Another regulation gene, R(2)tna, confers constitutivity at 13 C and does not map at the same locus as the R(2)tna gene.
摘要
加特纳，西奥多·K.（加利福尼亚大学戴维斯分校），以及莫妮卡·莱利。大肠杆菌色氨酸酶突变体的遗传分析。《细菌学杂志》89:319 - 325。1965年。——色氨酸酶结构基因tna以及色氨酸酶调控基因之一R(1)tna紧密连锁，位于大肠杆菌染色体上的pyr - E和ilv基因之间。该调控基因的突变形式在13℃时具有诱导性，在37℃时具有组成型，在37℃时具有超诱导性，它对该基因的野生型是显性的。另一个调控基因R(2)tna在13℃时赋予组成型，且其定位与R(2)tna基因不在同一位置。
