<p>This family describes the L-fucose permease in bacteria. L-fucose(6-deoxy-L-galactose) is a monosaccharide found in glycoproteins and cell wall polysaccharides. L-fucose is used in bacteria through an inducible pathway mediated by at least four enzymes: a permease, isomerase, kinase and an aldolase which are encoded by fucP, fucI, fucK, fucA respectively. </p> L-fucose permease
