Fucose permease and similar proteins of the Major Facilitator Superfamily of transporters; This subfamily is composed of L-fucose permease (also called L-fucose-proton symporter) and similar proteins such as glucose/galactose transporter and N-acetyl glucosamine transporter NagP. L-fucose permease facilitates the uptake of L-fucose across the boundary membrane with the concomitant transport of protons into the cell; it can also transport L-galactose and D-arabinose. Glucose/galactose transporter functions in the uptake of of glucose and galactose. The FucP-like subfamily belongs to the bacterial fucose permease, eukaryotic Major facilitator superfamily domain-containing protein 4 (FucP/MFSD4) family of the Major Facilitator Superfamily (MFS) of transporters. MFS proteins are thought to function through a single substrate binding site, alternating-access mechanism involving a rocker-switch type of movement.

L-fucose:H+ symporter permease; This family describes the L-fucose permease in bacteria. L-fucose(6-deoxy-L-galactose) is a monosaccharide found in glycoproteins and cell wall polysaccharides. L-fucose is used in bacteria through an inducible pathway mediated by atleast four enzymes: a permease, isomerase, kinase and an aldolase which are encoded by fucP, fucI, fucK, fucA respectively. The fuc genes belong to a regulon comprising of four linked operons: fucO, fucA, fucPIK and fucR. The positive regulator is encoded by fucR, whose protein responds to fuculose-1-phosphate, which acts as an effector. [Transport and binding proteins, Carbohydrates, organic alcohols, and acids]

Major Facilitator Superfamily; The Major Facilitator Superfamily (MFS) is a large and diverse group of secondary transporters that includes uniporters, symporters, and antiporters. MFS proteins facilitate the transport across cytoplasmic or internal membranes of a variety of substrates including ions, sugar phosphates, drugs, neurotransmitters, nucleosides, amino acids, and peptides. They do so using the electrochemical potential of the transported substrates. Uniporters transport a single substrate, while symporters and antiporters transport two substrates in the same or in opposite directions, respectively, across membranes. MFS proteins are typically 400 to 600 amino acids in length, and the majority contain 12 transmembrane alpha helices (TMs) connected by hydrophilic loops. The N- and C-terminal halves of these proteins display weak similarity and may be the result of a gene duplication/fusion event. Based on kinetic studies and the structures of a few bacterial superfamily members, GlpT (glycerol-3-phosphate transporter), LacY (lactose permease), and EmrD (multidrug transporter), MFS proteins are thought to function through a single substrate binding site, alternating-access mechanism involving a rocker-switch type of movement. Bacterial members function primarily for nutrient uptake, and as drug-efflux pumps to confer antibiotic resistance. Some MFS proteins have medical significance in humans such as the glucose transporter Glut4, which is impaired in type II diabetes, and glucose-6-phosphate transporter (G6PT), which causes glycogen storage disease when mutated.

Bacterial fucose permease, eukaryotic Major facilitator superfamily domain-containing protein 4, and similar proteins; This family is composed of bacterial L-fucose permease (FucP), eukaryotic Major facilitator superfamily domain-containing protein 4 (MFSD4) proteins, and similar proteins. L-fucose permease facilitates the uptake of L-fucose across the boundary membrane with the concomitant transport of protons into the cell; it can also transport L-galactose and D-arabinose. The MFSD4 subfamily consists of two vertebrate members: MFSD4A and MFSD4B. The function of MFSD4A is unknown. MFSD4B is more commonly know as Sodium-dependent glucose transporter 1 (NaGLT1), a primary fructose transporter in rat renal brush-border membranes that also facilitates sodium-independent urea uptake. The FucP/MFSD4 family belongs to the Major Facilitator Superfamily (MFS) of membrane transport proteins, which are thought to function through a single substrate binding site, alternating-access mechanism involving a rocker-switch type of movement.

Bacillus subtilis lincomycin resistance protein (LmrB) and similar multidrug resistance (MDR) transporters of the Major Facilitator Superfamily; This subfamily is composed of multidrug resistance (MDR) transporters including Bacillus subtilis lincomycin resistance protein LmrB, and several proteins from Escherichia coli such as the putative MDR transporters EmrB, MdtD, and YieQ. MDR transporters are drug/H+ antiporters (DHA) that mediate the efflux of a variety of drugs and toxic compounds, and confer resistance to these compounds. For example, MMR confers resistance to the epoxide antibiotic methylenomycin. This subfamily belongs to the Methylenomycin A resistance protein (also called MMR peptide) and similar multidrug resistance (MDR) transporters (MMR-like MDR transporter) family of the Major Facilitator Superfamily (MFS) of transporters. MFS proteins are thought to function through a single substrate binding site, alternating-access mechanism involving a rocker-switch type of movement.
