1.B.30.1.1
Outer envelope porin, OEP16.  Has an N-terminal 4 β-strand structure that forms the pore, and a C-terminla domain consisting of 3 α-helices (Steinkamp et al. 2000).  Cation-selective channel activity for amino acids and amines has been demonstrated following reconstitution (Linke et al. 2000; Ni et al. 2011).  It mediates metabolic fluxes during seed development and germination (Pudelski et al. 2012).
