6-phospho-beta-glucosidase A; Catalyzes the hydrolysis of phosphorylated beta-glucosides into glucose-6-phosphate (G-6-P) and aglycone. It has a high affinity for phosphorylated aromatic beta-glucosides (p-nitrophenyl-beta- glucoside, phenyl beta-glucoside, arbutin), with the exception of phosphorylated salicin, and a low affinity for phosphorylated beta- methyl-glucoside. Apparently, it has only a very limited role in the utilization of external beta-glucosides; Belongs to the glycosyl hydrolase 1 family.

Glucokinase; Not highly important in E.coli as glucose is transported into the cell by the PTS system already as glucose 6-phosphate.

Maltose outer membrane porin (maltoporin); Involved in the transport of maltose and maltodextrins, indispensable for translocation of dextrins containing more than three glucosyl moieties. A hydrophobic path ('greasy slide') of aromatic residues serves to guide and select the sugars for transport through the channel. Also acts as a receptor for several bacteriophages including lambda.
