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.

MFS-type transporter YcxA and similar proteins of the Major Facilitator Superfamily of transporters; This group is composed of uncharacterized bacterial MFS-type transporters including Bacillus subtilis YcxA and YbfB. YcxA has been shown to facilitate the export of surfactin in B. subtilis. The YcxA-like group belongs to the Monocarboxylate transporter -like (MCT-like) family of the Major Facilitator Superfamily (MFS) of membrane transport proteins. MFS proteins are thought to function through a single substrate binding site, alternating-access mechanism involving a rocker-switch type of movement.

4-hydroxybenzoate transporter PcaK and similar transporters of the Major Facilitator Superfamily; This aromatic acid:H(+) symporter subfamily includes Acinetobacter sp. 4-hydroxybenzoate transporter PcaK, Pseudomonas putida gallate transporter (GalT), Corynebacterium glutamicum gentisate transporter (GenK), Nocardioides sp. 1-hydroxy-2-naphthoate transporter (PhdT), Escherichia coli 3-(3-hydroxy-phenyl)propionate (3HPP) transporter (MhpT), and similar proteins. These transporters are involved in the uptake across the cytoplasmic membrane of specific aromatic compounds such as 4-hydroxybenzoate, gallate, gentisate (2,5-dihydroxybenzoate), 1-hydroxy-2-naphthoate, and 3HPP, respectively. The PcaK-like aromatic acid:H(+) symporter subfamily belongs to the Metazoan Synaptic Vesicle Glycoprotein 2 (SV2) and related small molecule transporter family (SV2-like) of the Major Facilitator Superfamily (MFS) of membrane transport proteins. MFS proteins are thought to function through a single substrate binding site, alternating-access mechanism involving a rocker-switch type of movement.

Glucose transporters (GLUTs) and other similar sugar transporters of the Major Facilitator Superfamily; This family is composed of glucose transporters (GLUTs) and other sugar transporters including fungal hexose transporters (HXT), bacterial xylose transporter (XylE), plant sugar transport proteins (STP) and polyol transporters (PLT), H(+)-myo-inositol cotransporter (HMIT), and similar proteins. GLUTs, also called Solute carrier family 2, facilitated glucose transporters (SLC2A), are a family of proteins that facilitate the transport of hexoses such as glucose and fructose. There are fourteen GLUTs found in humans; they display different substrate specificities and tissue expression. They have been categorized into three classes based on sequence similarity: Class 1 (GLUTs 1-4, 14); Class 2 (GLUTs 5, 7, 9, and 11); and Class 3 (GLUTs 6, 8, 10, 12, and HMIT). GLUT proteins are comprised of about 500 amino acid residues, possess a single N-linked oligosaccharide, and have 12 transmembrane segments. The GLUT-like 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.

Vesicular amine transporters 1 (VAT1) and 2 (VAT2), and similar transporters of the Major Facilitator Superfamily; Vesicular amine transporter 1 (VAT1 or VMAT1) is also called solute carrier family 18 member 1 (SLC18A1) or chromaffin granule amine transporter, while VAT2 (or VMAT2) is also called SLC18A2, synaptic vesicular amine transporter, or monoamine transporter. VATs (or VMATs) are responsible for the uptake of cytosolic monoamines into synaptic vesicles in monoaminergic neurons. VAT1 and VAT2 distinct pharmacological properties and tissue distributions. VAT1 is preferentially expressed in neuroendocrine cells and endocrine cells, where it transports biogenic monoamines, such as serotonin, from the cytoplasm into the secretory vesicles. VAT2 is primarily expressed in the CNS and is involved in the ATP-dependent vesicular transport of biogenic amine neurotransmitters including dopamine, norepinephrine, serotonin, and histamine into synaptic vesicles. VATs belong to the bacterial MdtG-like and eukaryotic solute carrier 18 (SLC18) 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.

Multidrug resistance protein MdtH and similar multidrug resistance (MDR) transporters of the Major Facilitator Superfamily; This family is composed of Escherichia coli MdtH and similar multidrug resistance (MDR) transporters from bacteria and archaea, many of which remain uncharacterized. 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. MdtH confers resistance to norfloxacin and enoxacin. MdtH-like MDR transporters belong 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.

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
