Salmonella typhimurium does not produce alkaline phosphatase (nor beta-galactosidase). Nevertheless, it has the function of the phoR+ regulatory gene but lacks the function of the lacI+ regulatory gene. Several periplasmic proteins are derepressed when cells of S. typhimurium are starved for inorganic phosphate. The role of phoR is discussed.
鼠伤寒沙门氏菌不产生碱性磷酸酶(也不产生β-半乳糖苷酶)。然而,它具有phoR⁺调节基因的功能,但缺乏lacI⁺调节基因的功能。当鼠伤寒沙门氏菌细胞缺乏无机磷酸盐时,几种周质蛋白会去阻遏。文中讨论了phoR的作用。
