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).

This image shows a graphical summary of conserved domains identified on the query sequence.
The Show Concise/Full Display button at the top of the page can be used to select the desired level of detail: only top scoring hits
(labeled illustration) or all hits
(labeled illustration).
Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.
click on the bars or triangles to view your query sequence embedded in a multiple sequence alignment of the proteins used to develop the corresponding domain model.
The table lists conserved domains identified on the query sequence. Click on the plus sign (+) on the left to display full descriptions, alignments, and scores.
Click on the domain model's accession number to view the multiple sequence alignment of the proteins used to develop the corresponding domain model.

(labeled illustration) Full Display shows all domain models, in each hit category below, that meet or exceed the RPS-BLAST threshold for statistical significance.
(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
specific hits meet or exceed a domain-specific e-value threshold
(illustrated example)
and represent a very high confidence that the query sequence belongs to the same protein family as the sequences use to create the domain model
non-specific hits
meet or exceed the RPS-BLAST threshold for statistical significance (default E-value cutoff of 0.01, or an E-value selected by user via the
advanced search options)
