Maltose transport system permease protein MalF, P2 domain (IPR029345)

Short name: MalF_P2

Overlapping homologous superfamilies


Domain relationships



The maltose transport system is composed of a periplasmic maltose-binding protein (MBP), two integral membrane proteins, MalF and MalG, and two copies of the cytoplasmic ATP-binding cassette MalK12 [PMID: 2026607]. The structures of the two transmembrane(TM) subunits, MalF and MalG, are composed of eight and six TM helices, respectively. The TM helices of MalF and MalG assemble into two crescent shaped structures with their concave surfaces facing each other and enclosing the maltose. MaltF consists of four periplasmic domains. This entry represents the second periplasmic domain (P2 domain) of MalF [PMID: 21825153, PMID: 18033289].
