*1.B.4.1.1









Fusion porin protein of 1115 aas with two domains that are homologous to members of family 1.B.4 at the N- and C-termini of this protein and a central domain homologous to members of family 1.B.13 proteins. These fusion proteins are found in several closely related species of α-proteobacteria such as those in the genuses, Methylosinus and Methylocystis (BL Reddy and MH Saier, unpublished observations).

*1.B.4.1.2









Fusion porin protein of 840 aas with an N-terminal domain that is homologous to members of family 1.B.13, and a C-terminal domain that is homologous to members of family 1.B.4 proteins.  It is 60% identical to the last two domains in 1.B.4.2.15 but it lacks the N-terminal domain of that protein.

Uncharacterized porin homologue of 242 aas.  Shows similarity with 9.B.184.1.1 which also shows similarity with members of 1.B.6; it is likely to be a porin.

High affinity Mn2+ (but not Co2+ or Cu2+) porin, MnoP (675 aas) (Hohle et al., 2011).  This protein seems to be a fusion protein between an Omp_b-br1 family porin (N-terminus) and an OprB porin (C-terminus).  It shows little sequence similiarity with the OprB family proteins of 1.B.19.
