Common NamePseudobactin
DescriptionPseudobactin is a siderophore belonging to the chemical class of catecholate-type iron chelators. Its chemical structure features a catechol moiety that facilitates iron binding, allowing it to effectively sequester ferric ions from the environment, which is crucial for bacterial survival in iron-limited conditions. Pseudobactin is involved in various biochemical pathways, particularly in the iron uptake mechanisms of Pseudomonas species, such as Pseudomonas capeferrum. The pseudobactin BN7/8 uptake (Pup) system not only imports iron but also regulates its own transcription through a complex signaling pathway involving the N-terminal signaling domain (NTSD) of the outer membrane transporter PupB and the C-terminal CSS domain (CCSSD) of the sigma regulator PupR (PMID:39334875 ). In the absence of ferric pseudobactin, these signaling components form a periplasmic complex that maintains a resting state (PMID:39334875 ). Pseudobactins are also noted for their interaction with iron nanoparticles, which have implications for controlling antibiotic-resistant strains such as Pseudomonas aeruginosa (PMID:31513733 ). Overall, pseudobactin plays a critical role in iron acquisition and regulatory pathways in Pseudomonas species (PMID:24818914 ).
