Phosphate-selective porin O/P (IPR010870)

Short name: Porin_O/P

Overlapping homologous superfamilies

Family relationships



This entry represents the bacterial phosphate-selective porins O and P. These are anion-specific porins, the binding sites of which has a higher affinity for phosphate than chloride ions. Porin O has a higher affinity for polyphosphates, while porin P has a higher affinity for orthophosphate [PMID: 1370289]. In Pseudomonas aeruginosa, porin O was found to be expressed only under phosphate-starvation conditions during the stationary growth phase [PMID: 1406271].
