title: The trehalose operon of Pseudomonas fluorescens ATCC 17400.
abstract: The trehalose operon of Pseudomonas fluorescens ATCC 17400 consists of treP, treA and treR. The gene treP codes for a putative enzyme II subunit of the phosphotransferase system that catalyzes the phosphorylation of trehalose together with its translocation across the cell membrane and treA encodes a putative phosphotrehalase, which hydrolyzes the incoming trehalose-6-phosphate into glucose and glucose-6-phosphate. Both genes are negatively regulated by TreR, a repressor of the FadR-GntR family of transcription regulators. The operon that is induced by trehalose present in the medium shows a high similarity both in the function of genes and in the regulation with the trehalose operon of Bacillus subtilis.
