Definition of malE1

• Curated sequence Q9S5Y1: MalE2; aka Maltose ABC transporter, periplasmic maltose-binding protein, component of The maltose, maltotriose, mannotetraose (MalE1)/maltose, maltotriose, trehalose (MalE2) porter (Nanavati et al., 2005). For MalG1 (823aas) and MalG2 (833aas), the C-terminal transmembrane domain with 6 putative TMSs is preceded by a single N-terminal TMS and a large (600 residue) hydrophilic region showing sequence similarity to MLP1 and 2 (9.A.14; e-12 & e-7) as well as other proteins
• Curated sequence Q9X0T1: MalE1; aka Maltose ABC transporter, periplasmic maltose-binding protein, component of The maltose, maltotriose, mannotetraose (MalE1)/maltose, maltotriose, trehalose (MalE2) porter (Nanavati et al., 2005). For MalG1 (823aas) and MalG2 (833aas), the C-terminal transmembrane domain with 6 putative TMSs is preceded by a single N-terminal TMS and a large (600 residue) hydrophilic region showing sequence similarity to MLP1 and 2 (9.A.14; e-12 & e-7) as well as other proteins
• Comment: Thermotoga maritima has malE1E2F1F2G1G2K; both SBPs bind maltose, so require only one to be present.
