Sugar ABC transporter substrate-binding protein; Involved in the high-affinity maltose membrane transport system. Initial receptor for the active transport of and chemotaxis toward maltooligosaccharides; Belongs to the bacterial solute-binding protein 1 family.

Maltose/maltodextrin transporter ATP-binding protein; Part of the ABC transporter complex MalEFGK involved in maltose/maltodextrin import. Responsible for energy coupling to the transport system; Belongs to the ABC transporter superfamily. Maltooligosaccharide importer (TC 3.A.1.1.1) family.

Maltose transporter permease; With MalKFE is involved in the transport of maltose into the cell; Derived by automated computational analysis using gene prediction method: Protein Homology.

Preprotein translocase subunit SecA; Part of the Sec protein translocase complex. Interacts with the SecYEG preprotein conducting channel. Has a central role in coupling the hydrolysis of ATP to the transfer of proteins into and across the cell membrane, serving both as a receptor for the preprotein-SecB complex and as an ATP-driven molecular motor driving the stepwise translocation of polypeptide chains across the membrane.

Maltose transporter membrane protein; With MalKGE is involved in maltose transport into the cell; Derived by automated computational analysis using gene prediction method: Protein Homology.

Hypothetical protein; Derived by automated computational analysis using gene prediction method: Protein Homology.

Transcriptional regulator MalT; Positively regulates the transcription of the maltose regulon whose gene products are responsible for uptake and catabolism of malto- oligosaccharides. Specifically binds to the promoter region of its target genes, recognizing a short DNA motif called the MalT box.

Membrane protein; OmpA is believed to be a porin, involved in diffusion of nonspecific small solutes across the outer membrane. It is the most abundant integral protein of the outer membrane of E. coli, and it is known to play a role as a phage receptor, a mediator of F-factor dependent conjugation, and in maintaining the structural shape of the outer membrane; 3a; II*; G; d; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the outer membrane OOP (TC 1.B.6) superfamily.

Vitamin B12/cobalamin outer membrane transporter; Involved in the active translocation of vitamin B12 (cyanocobalamin) across the outer membrane to the periplasmic space. It derives its energy for transport by interacting with the trans- periplasmic membrane protein TonB; Belongs to the TonB-dependent receptor family. BtuB (TC 1.B.14.3.1) subfamily.
