ascFCellobiose/arbutin/salicin-specific PTS enzymes, IIB and IC components; The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active -transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. This system is involved in arbutin, cellobiose, and salicin transport. (485 aa)
fucPL-fucose transporter; Mediates the uptake of L-fucose across the boundary membrane with the concomitant transport of protons into the cell (symport system). Can also transport L-galactose and D-arabinose, but at reduced rates compared with L-fucose. Is not able to transport L-rhamnose and L-arabinose. (438 aa)
ptsPPEP-protein phosphotransferase enzyme I; Component of the phosphoenolpyruvate-dependent nitrogen- metabolic phosphotransferase system (nitrogen-metabolic PTS), that seems to be involved in regulating nitrogen metabolism. Enzyme I-Ntr transfers the phosphoryl group from phosphoenolpyruvate (PEP) to the phosphoryl carrier protein (NPr). Could function in the transcriptional regulation of sigma-54 dependent operons in conjunction with the NPr (PtsO) and EIIA-Ntr (PtsN) proteins. Enzyme I-Ntr is specific for NPr. (748 aa)
araEArabinose transporter; Uptake of arabinose across the boundary membrane with the concomitant transport of protons into the cell (symport system). (472 aa)
cmtAPutative mannitol-specific PTS IIB and IIC components; The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. The enzyme II CmtAB PTS system is involved in D-mannitol transport. (462 aa)
cmtBPutative mannitol-specific enzyme IIA component of PTS; The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. The enzyme II CmtAB PTS system is involved in D-mannitol transport. (147 aa)
galPD-galactose transporter; Uptake of galactose across the boundary membrane with the concomitant transport of protons into the cell (symport system); Belongs to the major facilitator superfamily. Sugar transporter (TC 2.A.1.1) family. (464 aa)
