Definition of mtlA

• Curated sequence P00550: protein-Npi-phosphohistidine-D-mannitol phosphotransferase (EC 2.7.1.197). PTS system mannitol-specific EIICBA component; EC 2.7.1.-; EC 2.7.1.69. PTS system mannitol-specific EIICBA component; EIICBA-Mtl; EII-Mtl; EC 2.7.1.197. Mannitol porter (MtlA) (mannitol-1-P forming), the mannitol IICBA complex. mannitol-specific PTS enzyme IICBA component (EC 2.7.1.197; EC 2.7.1.198). mannitol-specific PTS enzyme IICBA component (EC 2.7.1.197; EC 2.7.1.198)
• Curated sequence Q9KKQ7: The mannitol/glucitol transporter, MtlA (IICBAMtl)
• Ignore hits to P42956 when looking for 'other' hits (PTS system, mannitol-specific IICBA component aka EIICBA-Mtl aka Mannitol-permease IIABC component aka Phosphotransferase enzyme II, CBA component aka EC 2.7.1.69 aka EII-Mtl, component of The mannitol porter (MtlA) (mannitol-1-P forming), MtlAF)
• Comment: polyol PTS system with EII-CBA all fused, known as mtlA in E. coli (TC 4.A.2.1.2). Also includes TC 4.A.2.1.12 (Q9KKQ7). TC 4.A.2.1.5 (P42956) is the B. subtilis mannitol transporter but probably has weak activity no sorbitol (PMC222339). so exclude it. Not known if the homologs from Geobacillus stearothermophilus (P50852) or Clostridium acetobutylicum (O65989) [which lack the A component], which are mannitol transporters, are capable of sorbitol transport
