Fatty acid outer membrane porin. Gated by high affinity ligand (fatty acid) binding which causes conformational changes in the N-terminus that open up a channel for substrate diffusion (Lepore et al., 2011).  May function in the transport of phenylpropanoids (resveratrol, naringenin and rutin) (Zhou et al. 2014).
