== Function ==
== Function ==
[[http://www.uniprot.org/uniprot/MALF_ECOLI MALF_ECOLI]] Part of the binding-protein-dependent transport system for maltose; probably responsible for the translocation of the substrate across the membrane. [[http://www.uniprot.org/uniprot/MALE_ECOLI MALE_ECOLI]] Involved in the high-affinity maltose membrane transport system MalEFGK. Initial receptor for the active transport of and chemotaxis toward maltooligosaccharides.  
[https://www.uniprot.org/uniprot/MALK_ECOLI MALK_ECOLI] Part of the ABC transporter complex MalEFGK involved in maltose/maltodextrin import. Responsible for energy coupling to the transport system.
