Arginine Biosynthesis Modulates Pyoverdine Production and Release in Pseudomonas putida as Part of the Mechanism of Adaptation to Oxidative Stress.

The KT2440 study reports that an individual argJ mutant remains arginine prototrophic, leaving its contribution relative to ArgA and ArgE unresolved.

UniProtKB entry for PSEPK ArgJ

Curated catalytic chemistry or specific family classification supports the inferred target function.

"Reaction=N(2)-acetyl-L-ornithine + L-glutamate = N-acetyl-L-glutamate + L-ornithine;"

OpenScientist functional synthesis for PSEPK ArgJ

The report retrieves both defining ArgJ reactions for the exact target accession. Its claims that the cyclic route is dominant in KT2440 and that target-specific inhibition or expression is established are not used; the direct KT2440 mutant result above also corrects its statement that no knockout phenotype has been published.
