A two-component response regulator, gltR, is required for glucose transport activity in Pseudomonas aeruginosa PAO1

Abstract

A 729-bp open reading frame (gltR) was identified in Pseudomonas aeruginosa PAO1 that encodes a product homologous to the two-component response regulator family of proteins. Disruption of gltR caused loss of glucose transport activity. Restoration of gltR resulted in wild-type levels of glucose transport. These findings indicate that gltR is required for expression of the glucose transport system in P. aeruginosa.
