Cloning and characterization of Pseudomonas putida genes encoding the phosphate-specific transport system.

A same-species PRS2000 study established PstSCAB-dependent phosphate uptake, but it does not identify Q88JJ1 or the KT2440 PP_2656 operon.

"The pstSCAB genes of Pseudomonas putida PRS2000, encoding the phosphate (Pi)-specific transport (Pst) system, were cloned."

OpenScientist pathway and taxon report for PSEPK Pst phosphate uptake

The report distinguishes the PP_2656-PP_2659 Pst-like operon from the Pho-linked PP_5326-PP_5329 operon and leaves the former's physiological role unresolved.
