UniProt functional annotation for P68183

UniProt code: P68183.

Organism: Escherichia coli (strain K12).
Taxonomy: Bacteria; Proteobacteria; Gammaproteobacteria; Enterobacterales; Enterobacteriaceae; Escherichia.
 
Function: Part of the ABC transporter complex MalEFGK involved in maltose/maltodextrin import. Probably responsible for the translocation of the substrate across the membrane. {ECO:0000269|PubMed:2026607, ECO:0000269|PubMed:2155217}.
 
Subunit: The complex is composed of two ATP-binding proteins (MalK), two transmembrane proteins (MalG and MalF) and a solute-binding protein (MalE). Protein stability and stable complex formation require YidC. {ECO:0000269|PubMed:10809785, ECO:0000269|PubMed:18456666, ECO:0000269|PubMed:2026607, ECO:0000269|PubMed:2155217}.
Subcellular location: Cell inner membrane {ECO:0000269|PubMed:18456666, ECO:0000269|PubMed:2233678}; Multi-pass membrane protein {ECO:0000255|PROSITE-ProRule:PRU00441, ECO:0000269|PubMed:18456666, ECO:0000269|PubMed:2233678}.
Miscellaneous: When MalF EAA loop mutations are made concomitantly with MalG EAA loop mutations, a complete loss of transport and complex formation is observed. This suggests that the MalF-MalG interaction may be important for the proper assembly and also for the correct function of the transporter.
Similarity: Belongs to the binding-protein-dependent transport system permease family. MalFG subfamily. {ECO:0000305}.
