Creatine utilization as a sole nitrogen source in Pseudomonas putida KT2440 is transcriptionally regulated by CahR
creatine regulon is small and electrophoretic mobility shift demonstrates specific CahR binding only at the creA promoter suggesting much of the regulon is due to induction by downstream products. This study identifies ligand specificity and provides biological function to a previously uncharacterized GATR, contributing to our understanding of bacterial organic nitrogen compound metabolism. Overall design: Examination of growth and gene expression of Pseudomonas putida wild type and ?cahR strains in response to creatine.
