efflux transporter, outer membrane factor (OMF) lipoprotein, NodT family; Members of this model comprise a subfamily of the Outer Membrane Factor (TCDB 1.B.17) porins. OMF proteins operate in conjunction with a primary transporter of the RND, MFS, ABC, or PET systems, and a MFP (membrane fusion protein) to tranport substrates across membranes. The complex thus formed allows transport (export) of various solutes (heavy metal cations; drugs, oligosaccharides, proteins, etc.) across the two envelopes of the Gram-negative bacterial cell envelope in a single energy-coupled step. Current data suggest that the OMF (and not the MFP) is largely responsible for the formation of both the trans-outer membrane and trans-periplasmic channels. The roles played by the MFP have yet to be determined. [Cellular processes, Detoxification, Transport and binding proteins, Porins]

Outer membrane efflux protein; The OEP family (Outer membrane efflux protein) form trimeric channels that allow export of a variety of substrates in Gram negative bacteria. Each member of this family is composed of two repeats. The trimeric channel is composed of a 12 stranded all beta sheet barrel that spans the outer membrane, and a long all helical barrel that spans the periplasm.

type I secretion outer membrane protein, TolC family; Members of this model are outer membrane proteins from the TolC subfamily within the RND (Resistance-Nodulation-cell Division) efflux systems. These proteins, unlike the NodT subfamily, appear not to be lipoproteins. All are believed to participate in type I protein secretion, an ABC transporter system for protein secretion without cleavage of a signal sequence, although they may, like TolC, participate also in the efflux of smaller molecules as well. This family includes the well-documented examples TolC (E. coli), PrtF (Erwinia), and AprF (Pseudomonas aeruginosa).

RND family efflux transporter, MFP subunit; This model represents the MFP (membrane fusion protein) component of the RND family of transporters. RND refers to Resistance, Nodulation, and cell Division. It is, in part, a subfamily of pfam00529 (Pfam release 7.5) but hits substantial numbers of proteins missed by that model. The related HlyD secretion protein, for which pfam00529 is named, is outside the scope of this model. Attributed functions imply outward transport. These functions include nodulation, acriflavin resistance, heavy metal efflux, and multidrug resistance proteins. Most members of this family are found in Gram-negative bacteria. The proposed function of MFP proteins is to bring the inner and outer membranes together and enable transport to the outside of the outer membrane. Note, however, that a few members of this family are found in Gram-positive bacteria, where there is no outer membrane. [Transport and binding proteins, Unknown substrate]
