Abstract
Alkaline phosphatase, the phoA product, is synthesized constitutively in phoR mutants. This constitutive synthesis, which is independent of phosphate control, varies with changes in the osmolarity of the growth medium; phoA expression increases with increasing osmolarity. Maximum expression of the osmoregulated genes phoA, ompC, and ompF was achieved by osmotic manipulation of minimal medium; complex media repressed their expression.
摘要
碱性磷酸酶，即phoA产物，在phoR突变体中组成性合成。这种独立于磷酸盐调控的组成性合成随生长培养基渗透压的变化而变化；phoA表达随渗透压升高而增加。通过对基本培养基进行渗透操作可实现渗透调节基因phoA、ompC和ompF的最大表达；复合培养基会抑制它们的表达。
