PTS transporter subunit EIIC
The bacterial phosphoenolpyruvate: sugar phosphotransferase system (PTS) is a multi-protein system involved in the regulation of a variety of metabolic and transcriptional processes. The sugar-specific permease of the PTS consists of three domains (IIA, IIB and IIC). The IIC domain catalyses the transfer of a phosphoryl group from IIB to the sugar substrate. [1]. 9689210.

PTS system, Lactose/Cellobiose specific IIB subunit
The bacterial phosphoenolpyruvate: sugar phosphotransferase system (PTS) is a multi-protein system involved in the regulation of a variety of metabolic and transcriptional processes. The lactose/cellobiose-specific family are one of four structurally and functionally distinct group IIB PTS system cytoplasmic enzymes. The fold of IIB cellobiose shows similar structure to mammalian tyrosine phosphatases. This family also contains the fructose specific IIB subunit. [1]. 9041631.

PTS fructose transporter subunit IIC
PTS fructose transporter subunit IIC forms the translocation channel and contains the specific substrate-binding site of the phosphoenolpyruvate-dependent sugar phosphotransferase system (PTS) that catalyzes the phosphorylation of incoming sugar substrates concomitant with their translocation across the cell membrane
fructose-specific PTS transporter subunit EIIC
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 (PF02378) 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.
fructose PTS transporter subunit IIB
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 PTS components of unknown specificities. The fructose components of this family phosphorylate fructose on the 1-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 family is specific for the IIB domain of the fructose PTS transporters.
