permease

Responsible for transport of beta-galactosides into the cell, with the concomitant import of a proton (symport system). Can transport lactose, melibiose, lactulose or the analog methyl-1-thio-beta,D-galactopyranoside (TMG), but not sucrose or fructose. The substrate specificity is directed toward the galactopyranosyl moiety of the substrate. Lactose permease Protein, E. coli, Recombinant (His) is expressed in E. coli expression system with N-10xHis tag. The predicted molecular weight is 34.4 kDa and the accession number is P02920.

Sodium ascorbate cotransporter. Mediates electrogenic uptake of vitamin C, with a stoichiometry of 2 Na(+) for each ascorbate. SLC23A2 Protein, Human, Recombinant (His) is expressed in E. coli expression system with C-6xHis tag. The predicted molecular weight is 71.3 kDa and the accession number is Q9UGH3.

Could be part of an ABC transporter complex. RT0041 Protein, Rickettsia typhi, Recombinant (His & Myc) is expressed in E. coli expression system with N-10xHis and C-Myc tag. The predicted molecular weight is 15.7 kDa and the accession number is Q68XW4.

Essential for the uptake of the murein peptide L-alanyl-gamma-D-glutamyl-meso-diaminopimelate. Also transports some alpha-linked peptides such as Pro-Phe-Lys with low affinity. The transport is effected by the oligopeptide permease system.

This protein is a component of the oligopeptide permease, a binding protein-dependent transport system, it binds peptides up to five amino acids long with high affinity.
