Salmonella typhimurium contains an anion-selective outer membrane porin induced by phosphate starvation.
A mutant of Salmonella typhimurium was selected that is constitutive for the pho regulon. It exhibited constitutive glycerol-3-phosphate transport activity and synthesized a new outer membrane porin. Upon measurement of porin activity in black lipid films, it exhibited anion selectivity. It therefore appears analogous to the Escherichia coli PhoE porin.
