4.A.6.1.13
Fucosyl-α-1,3-N-acetylglucosamine PTS uptake porter, AlfEFG (next to an operon encoding a fucosidase (AlfB) and a transcriptional regulator of the GntR family, AlfR).  The fucosidase is specific for this disaccharide which is present in mammalian glycoproteins, glycolipids and milk (Rodríguez-Díaz et al. 2012).  Uptake is dependent of AlfF but not on the PTS Enzyme I, suggesting that uptake does not require phosphorylation, consistent with the activity of AlfB as a fucosidase.  Only the glucosamine moiety is utilized and the fucose moiety, after hydrolysis, is excreted (Rodríguez-Díaz et al. 2012).
