*4.A.6.1.1 | The mannose (glucose, 2-deoxyglucose, glucosamine, N-acetylglucosamine, N-acetylmannosamine, mannosamine and fructose) PTS porter/group translocator, ManXYZ (Rephaeli and Saier 1980; Plumbridge 2015). Catalyzes xylose facilitated diffusion in lactobacilli. The order of D-sugar substrate affinities is: glucose > mannose > 2-deoxyglucose > N-acetylglucosamine > glucosamine > N-acetylmannosamine > mannosamine > fructose (Rephaeli and Saier 1980). The mechanism appears to be rapid equilibrium, random, bi-bi sequential (Rephaeli and Saier 1980). L-sugars are not transported.

*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). | Bacteria |

The system is designated the GnbABCD system where GnbA = IIA, GnbB = IIB, GnbC = IIC, and GnbD = IID of the mannose-type PTS Enzyme II complex. These disaccaride substrates are human milk oligosaccharides and glycoconjugates (Bidart et al. 2014). | Bacteria |

|
*4.A.6.1.19 | PTS uptake system for glucoselysine and fructoselysine, GfrABCD (Miller et al. 2015). Two glycases, GfrE and GfrF, are requred for the utilization of these two compounds for growth, respectively, and GfrF was shown to hydrolyze fructoselysine-6-P to lysine and fructose-6-P. Expression of the operon, gfrABCDEF, is regulated by a transcriptional activator, GfrR and sigma factor RpoN (Miller et al. 2015). GfrD affects proteolytic processing, a necessary but insufficient step for CadC activation, rendering CadC able to activate target genes involved in lysine metabolism (Lee et al. 2013). | Bacteria |
