Abstract

In Erwinia carotovora subsp. carotovora EC14 grown under conditions of phosphate starvation, alkaline phosphatase, and binding protein dependent transport systems for inorganic phosphate andsn-glycerol-3-phosphate were simultaneously derepressed. Analysis of periplasmic protein profiles from phosphate-starved cells revealed four starvation-inducible proteins. Three of these proteins corresponded to alkaline phosphatase, a binding protein for phosphate, and a binding protein for.sn-glycerol-3-phosphate, respectively. The coordinate derepression of these proteins demonstrates the existence of a phosphate regulon similar to that found in other members of the family Enterobacteriaceae.Key words: Erwinia, phosphate, regulon, alkaline phosphatase, binding protein.
