RESUMO
The expression of the ugp-dependent sn-glycerol-3-phosphate transport system that is part of the pho regulon was studied in mutants of Escherichia coli K-12 containing regulatory mutations of the pho regulon. The phoR and phoST gene products exerted a negative control on the expression of ugp. Induction of the system was positively controlled by the phoB, phoM, and phoR gene products. Using a ugp-lacZ operon fusion, we showed that the ugp and phoA genes were coordinately derepressed and repressed.
