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).
