>gnl|CDD|119392 cd06174, MFS, 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.

>gnl|CDD|130366 TIGR01299, synapt_SV2, synaptic vesicle protein SV2. This model
describes a tightly conserved subfamily of the larger
family of sugar (and other) transporters described by
PFAM model pfam00083. Members of this subfamily include
closely related forms SV2A and SV2B of synaptic vesicle
protein from vertebrates and a more distantly related
homolog (below trusted cutoff) from Drosophila
melanogaster. Members are predicted to have two sets of
six transmembrane helices.
