Definition of thuK

• Curated sequence P9WQI3: Trehalose import ATP-binding protein SugC; EC 7.5.2.-. PROBABLE SUGAR-TRANSPORT ATP-BINDING PROTEIN ABC TRANSPORTER SUGC, component of The trehalose-recycling ABC transporter, LpqY-SugA-SugB-SugC (essential for virulence)
• Curated sequence Q9YGA6: Trehalose/maltose import ATP-binding protein MalK; EC 7.5.2.1
• Curated sequence Q72L52: Sugar-binding transport ATP-binding protein aka MalK1 aka TT_C0211, component of The trehalose/maltose/sucrose/palatinose porter (TTC1627-9) plus MalK1 (ABC protein, shared with 3.A.1.1.24) (Silva et al. 2005; Chevance et al., 2006). The receptor (TTC1627) binds disaccharide alpha-glycosides, namely trehalose (alpha-1,1), sucrose (alpha-1,2), maltose (alpha-1,4), palatinose (alpha-1,6) and glucose
• Curated sequence Q9R9Q4: ThuK aka RB0314 aka SMB20328, component of Trehalose/maltose/sucrose porter (trehalose inducible). ABC transporter for D-Trehalose, ATPase component
• Curated sequence Q9X103: MalK; aka Sugar ABC transporter, ATP-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
