Abstract
Mutations in apeR, a regulatory locus of the outer membrane esterase apeE from Salmonella enterica serovar Typhimurium, were shown to be alleles of the pstSCAB-phoU high-affinity phosphate transport operon. Expression of apeE was induced by phosphate limitation, and this induction required the phoBR phosphate regulatory system.
