A functional gltB gene is essential for utilization of acidic amino acids and expression of periplasmic glutaminase/asparaginase (PGA) by Pseudomonas putida KT2440.

Molecular genetics and genomics : MGG - 1 Feb 2004

Sonawane A M, Röhm K H

Abstract excerpt

Pseudomonas putida KT2440, a root-colonizing fluorescent pseudomonad, is capable of utilizing acidic amino acids (Asp and Glu) and their amides (Asn and Gln) as its sole source of carbon and nitrogen. The uptake of Gln and Asn is facilitated by a periplasmic glutaminase/asparaginase (PGA), which hydrolyses Asn and Gln to the respective dicarboxylates. Here, we describe transposon mutagenesis of P. putida KT2440...
