1.B.5.1.1 | Outer membrane phosphate-selective porin OprP (PorP) of 440 aas. Binds and transports a variety of mono, di- and trivalent anions (Benz et al. 1993). An arginine in the pore determines the anion selectivity (Modi et al. 2013). Residues involved in anion affinity and a preference for Pi versus P2 have been identified (Modi et al. 2015). Both monomeric and trimeric OprP are belived to maintain their anion selectivity (Niramitranon et al. 2016). The phosphonic-acid antibiotic fosfomycin is highly permeable through the OprO and OprP channels (Citak et al. 2018). | Bacteria |
Pseudomonadota | OprP of Pseudomonas aeruginosa |
|
1.B.5.1.2 | Pyrophosphate-selective porin OprO (Hancock et al. 1992). The residue basis for the selectivity of P2 over Pi has been determined and involves two residues (Modi et al. 2015). The phosphonic-acid antibiotic fosfomycin is highly permeable through the OprO and OprP channels (Citak et al. 2018). Fosfidomycin is also transported (Lapierre and Hub 2023). In OprO, there is a lysine cluster that is responsible for anion selectivity (Piselli et al. 2023). | Bacteria |
