PTS system, fructose subfamily, IIC component; This model represents the IIC component, or IIC region of a IIABC or IIBC polypeptide of a phosphotransferase system for carbohydrate transport. Members of this family belong to the fructose-specific subfamily of the broader family (pfam02378) of PTS IIC proteins. Members should be found as part of the same chain or in the same operon as fructose family IIA (TIGR00848) and IIB (TIGR00829) protein regions. A number of bacterial species have members in two different branches of this subfamily, suggesting some diversity in substrate specificity of its members.

PTS_IIB_fructose: subunit IIB of enzyme II (EII) of the fructose-specific phosphoenolpyruvate:carbohydrate phosphotransferase system (PTS). In this system, EII (also referred to as FruAB) is a fructose-specific permease made up of two proteins (FruA and FruB) each containing 3 domains. The FruA protein contains two tandem nonidentical IIB domains and a C-terminal IIC transmembrane domain. Both IIB domains of FruA are included in this alignment. The FruB protein (also referred to as diphosphoryl transfer protein) contains a IIA domain, a domain of unknown function, and an Hpr-like domain called FPr (fructose-inducible HPr). This familiy also includes the IIB domains of several fructose-like PTS permeases including the Frv permease encoded by the frvABXR operon, the Frw permease encoded by the frwACBD operon, the Frx permease encoded by the hrsA gene, and the Fry permease encoded by the fryABC (ypdDGH) operon. FruAB takes up exogenous fructose, releasing the 1-phosphate ester in to the cytoplasm in preparation for metabolism primarily via glycolysis. The IIB domain fold includes a central four-stranded parallel open twisted beta-sheet flanked by alpha-helices on both sides. The seven major PTS systems with this IIB fold include fructose, chitobiose/lichenan, ascorbate, lactose, galactitol, mannitol, and a sensory system with similarity to the bacterial bgl system.

PTS system, fructose subfamily, IIA component; 4.A.2 The PTS Fructose-Mannitol (Fru) Family Bacterial PTS transporters transport and concomitantly phosphorylate their sugar substrates, and typically consist of multiple subunits or protein domains. The Fru family is a large and complex family which includes several sequenced fructose and mannitol-specific permeases as well as several putative PTS permeases of unknown specificities. The fructose permeases of this family phosphorylate fructose on the 1-position. Those of family 4.6 phosphorylate fructose on the 6-position. The Fru family PTS systems typically have 3 domains, IIA, IIB and IIC, which may be found as 1 or more proteins. The fructose and mannitol transporters form separate phylogenetic clusters in this family. This model is specific for the IIA domain of the fructose PTS transporters. Also similar to the Enzyme IIA Fru subunits of the PTS, but included in TIGR01419 rather than this model, is enzyme IIA Ntr (nitrogen), also called PtsN, found in E. coli and other organisms, which may play a solely regulatory role.

PTS_IIB: subunit IIB of enzyme II (EII) is the central energy-coupling domain of the phosphoenolpyruvate:carbohydrate phosphotransferase system (PTS). In the multienzyme PTS complex, EII is a carbohydrate-specific permease consisting of two cytoplasmic domains (IIA and IIB) and a transmembrane channel IIC domain. The IIB domain fold includes a central four-stranded parallel open twisted beta-sheet flanked by alpha-helices on both sides. The seven major PTS systems with this IIB fold include chitobiose/lichenan, ascorbate, lactose, galactitol, mannitol, fructose, and a sensory system with similarity to the bacterial bgl system. The PTS is found only in bacteria, where it catalyzes the transport and phosphorylation of numerous monosaccharides, disaccharides, polyols, amino sugars, and other sugar derivatives. The four proteins (domains) forming the PTS phosphorylation cascade (EI, HPr, EIIA, and EIIB), can phosphorylate or interact with numerous non-PTS proteins thereby regulating their activity.

PTS IIA-like nitrogen-regulatory protein PtsN; This model describes a full-length protein of about 160 residues closely related to the fructose-specific phosphotransferase (PTS) system IIA component. It is a regulatory protein found only in species with a phosphoenolpyruvate-protein phosphotransferase (enzyme I of PTS systems) and an HPr-like phosphocarrier protein, but not all species have a IIC-like permease. Members of this family are found in Proteobacteria, Chlamydia, and the spirochete Treponema pallidum. [Signal transduction, PTS]
