1.B.70 The Outer Membrane Channel (OMC) Family

The OMC family consists of putative porins that are homologous to many other porins although this particular family is poorly characterized.  These proteins are derived from proteobacteria of the alpha, beta and gamma subphyla as well as chlorobi and planctomycetes and probably other phyla.  They are therefore wide spead in Gram-negative bacteria.
