Lactose permease Protein, E. coli, Recombinant (His)

Description: 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.
