Na+/melibiose symporter or related transporter [Carbohydrate transport and metabolism].

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.

MFS/sugar transport protein. This family is part of the major facilitator superfamily of membrane transport proteins.

Exo-beta-1,3-glucanase, GH17 family [Carbohydrate transport and metabolism].

sugar (Glycoside-Pentoside-Hexuronide) transporter. The Glycoside-Pentoside-Hexuronide (GPH):Cation Symporter Family (TC 2.A.2) GPH:cation symporters catalyze uptake of sugars in symport with a monovalent cation (H+ or Na+). Members of this family includes transporters for melibiose, lactose, raffinose, glucuronides, pentosides and isoprimeverose. Mutants of two groups of these symporters (the melibiose permeases of enteric bacteria, and the lactose permease of Streptococcus thermophilus) have been isolated in which altered cation specificity is observed or in which sugar transport is uncoupled from cation symport (i.e., uniport is catalyzed). The various members of the family can use Na+, H+ or Li, Na+ or Li+, H+ or Li+, or only H+ as the symported cation. All of these proteins possess twelve putative transmembrane a-helical spanners.
