Definition of levDE

• Curated sequence CH_088329: PTS system mannose-specific EIIAB component; EC 2.7.1.-; EC 2.7.1.69. PTS system mannose-specific EIIAB component; EIIAB-Man; EIII-Man; EC 2.7.1.191. PTNA aka MANX aka PTSL aka GPTB aka B1817, component of The mannose (glucose, 2-deoxyglucose, glucosamine, N-acetylglucosamine, N-acetylmannosamine, mannosamine and fructose) PTS porter/group translocator, ManXYZ (Rephaeli and Saier 1980; Plumbridge 2015). Catalyzes xylose facilitated diffusion in lactobacilli. The order of D-sugar substrate affinities is: glucose > mannose > 2-deoxyglucose > N-acetylglucosamine > glucosamine > N-acetylmannosamine > mannosamine > fructose. mannose-specific PTS enzyme IIAB component (EC 2.7.1.191; EC 2.7.1.199; EC 2.7.1.193). mannose-specific PTS enzyme IIAB component
• Curated sequence Q04GK1: Phosphotransferase system, mannose/fructose-specific component IIA, component of The hexose (glucose and fructose demonstrated) PTS uptake system
• Curated sequence Q5M5W6: ManL, component of The glucose/mannose/2-deoxyglucose/fructose phosphotransferase systems (phosphorylates without transport), ManLMN
• Ignore hits to Q9S4L5 when looking for 'other' hits (protein-Npi-phosphohistidine-D-mannose phosphotransferase (EC 2.7.1.191))
• Ignore hits to D2BKY7 when looking for 'other' hits (Mannose-specificPTS system, IIAB component, component of Mannose enzyme II complex, IIAB, IIC, IID. IIC/IID serve allows entry of some bacteriocins including pediocin (class IIa) and lactococcin A (class IIc) (Kjos et al., 2011). Transports and phosphorylates Glucose, Mannose and Glucosamine)
• Comment: Q9S4L5 is nearly identical to Q5M5W6; not sure if it acts on fructose or not. D2BKY7 is very similar to Q5M5W6 and has been studied mostly as a receptor to bacteriocins; not sure if it acts on fructose or not.
