Metabolite Identification
Common Namepseudopaline
Descriptionpseudopaline is a metallophore belonging to the class of opines. Its chemical structure enables it to function as a narrow spectrum ion chelator, specifically complexing with zinc ions (Zn2+). Pseudopaline is synthesized by Pseudomonas aeruginosa and plays a role in the production of polyamines and various siderophores, which are critical for metal ion acquisition in microbial environments (PMID:39155120 ). The biosynthetic pathway of pseudopaline involves gene clusters related to secondary metabolite synthesis, with seven clusters conserved across different strains of Pseudomonas (PMID:39597652 ). Additionally, it is secreted via the Drug Metabolite Transporter (DMT) family, highlighting its importance in metallophore export (PMID:37930543 ). The secretion of pseudopaline can be induced by environmental stressors such as chromium (Cr), which enhances both its production and import into bacterial cells, suggesting a role in cellular responses to metal ion availability (PMID:36099868 ). Overall, pseudopaline's ability to chelate Zn2+ is crucial for processes like transcription regulation and DNA repair in bacteria (PMID:36099868 ).
