Phosphorylation of GltX by HipA prevents it from being charged, leading to an increase in uncharged tRNA(Glu). This induces amino acid starvation and the stringent response via RelA/SpoT and increased (p)ppGpp levels, which inhibits replication, transcription, translation and cell wall synthesis, reducing growth and leading to multidrug resistance and persistence (PubMed:24095282, PubMed:24343429). Overexpression of GltX prevents HipA-induced growth arrest, persister formation and increases in (p)ppGpp levels (PubMed:24343429, PubMed:28430938).
