Folate-biopterin transporter of the Major Facilitator Superfamily of transporters; The Folate-biopterin transporter (FBT) family includes folate carriers related to those of trypanosomatids in higher plant plastids and cyanobacteria. FBT mediates folate monoglutamate transport involved in tetrahydrofolate biosynthesis. It also mediates transport of antifolates, such as methotrexate and aminopterin. The FBT 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.

BT1 family; Members of this family are transmembrane proteins. Several are Leishmania putative proteins that are thought to be pteridine transporters. One such protein Swiss:Q25272, previously termed (and is still annotated as) ORFG, was shown to encode a biopterin transport protein using null mutants, thus being subsequently renamed BT1. The significant similarity of ORFG/BT1 to Trypanosoma brucei ESAG10 (a putative transmembrane protein and another member of this family) was previously noted. This family also contains five putative Arabidopsis thaliana proteins of unknown function. In addition, it also contains two predicted prokaryotic proteins (from the cyanobacteria Synechocystis and Synechococcus).

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.

Salmonella enterica Na+/melibiose symporter MelB and similar transporters of the Major Facilitator Superfamily; This family is composed of Salmonella enterica Na+/melibiose symporter MelB, Major Facilitator Superfamily domain-containing proteins, MFSD2 and MFSD12, and other sugar transporters. MelB catalyzes the electrogenic symport of galactosides with Na+, Li+ or H+. The MFSD2 subfamily is composed of two vertebrate members, MFSD2A and MFSD2B. MFSD2A is more commonly called sodium-dependent lysophosphatidylcholine symporter 1 (NLS1). It is an LPC symporter that plays an essential role for blood-brain barrier formation and function. Inactivating mutations in MFSD2A cause a lethal microcephaly syndrome. MFSD2B is a potential risk or protect factor in the prognosis of lung adenocarcinoma. MelB-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.

Major facilitator superfamily domain containing 3 protein; Major facilitator superfamily domain containing 3 protein (MFSD3) is a predicted acetyl-CoA transporter. As an atypical putative membrane-bound solute carrier (SLC), MFSD3 is most likely to be functionally active in the plasma membrane and not in any intracellular organelles. MFSD3 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 YxlH and similar transporters of the Major Facilitator Superfamily; This subfamily is composed of Bacillus subtilis YxlH uncharacterized MFS-type transporter YxlH and similar proteins. The biological function of YxlH remains unclear. The YxlH-like subfamily belongs 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.

Bacteriochlorophyll delivery (BCD) family, also called PucC family, of the Major Facilitator Superfamily; The bacteriochlorophyll delivery (BCD) family, also called PucC family, is composed of the PucC protein and related proteins including LhaA (also called ORF477 and F1696) and bacteriochlorophyll synthase 44.5 kDa chain (also called ORF428). These proteins are found in photosynthetic organisms. Rhodobacter capsulatus LhaA and PucC are implicated in light-harvesting complex 1 and 2 (LH1 and LH2) assembly. PucC may function to shepherd or sequester LH2 alpha and beta proteins to facilitate proper assembly, as well as deliver bacteriochlorophyll a to nascent LH2 complexes. The BCD 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.
