Mutants expressing a novel enzyme I of the phosphoenolpyruvate:sugar phosphotransferase system, termed enzyme I, were isolated from strains of Salmonella typhimurium which were deleted for the HPr and enzyme I structural genes. The mutations lay in a newly defined gene, termed ptsJ, which mapped on the S. typhimurium chromosome between the ptsHI operon and the cysA gene.
糖磷酸转移酶系统新型酶I(称为酶I)的突变体,这些菌株的HPr和酶I结构基因已缺失。这些突变位于一个新定义的基因中,称为ptsJ,它定位在鼠伤寒沙门氏菌染色体上ptsHI操纵子和cysA基因之间。
