Mutations in the ack (acetate kinase) and pta (phosphotransacetylase) genes in Salmonella typhimurium were characterized and determined to be analogous to those of previously described Escherichia coli mutants. We established that in both bacterial species these genes were cotransducible with the neighboring histidine transport operon and were distally located relative to purF. pta mutants were sensitive to the dye alizarin yellow and were unable to grow on medium containing inositol as a carbon source. We selected mutants of both species with deletions covering both the ack and the pta genes; some deletions extended into the histidine transport operon.
对鼠伤寒沙门氏菌中ack(乙酸激酶)和pta(磷酸转乙酰酶)基因的突变进行了表征,并确定它们与先前描述的大肠杆菌突变体类似。我们确定,在这两种细菌中,这些基因与相邻的组氨酸转运操纵子共转导,并且相对于purF位于远端。pta突变体对染料茜素黄敏感,并且无法在含有肌醇作为碳源的培养基上生长。我们筛选了这两种细菌的突变体,其缺失覆盖了ack和pta基因;一些缺失延伸到组氨酸转运操纵子中。
