While the Lac family usually consists of two polypeptide components IIA and IICB, the Chb permease of E. coli consists of three IIA, IIB and IIC. This family is specific for the IIB subunit of the Lac PTS family. [Transport and binding proteins, Carbohydrates, organic alcohols, and acids, Signal transduction, PTS]

PTS_IIB_chitobiose_lichenan: subunit IIB of enzyme II (EII) of the N,N-diacetylchitobiose-specific and lichenan-specific phosphoenolpyruvate:carbohydrate phosphotransferase system (PTS). In these systems, EII is either a lichenan- or an N,N-diacetylchitobiose-specific permease with two cytoplasmic domains (IIA and IIB) and a transmembrane channel IIC domain. In the chitobiose system, these subunits are expressed as separate proteins from chbA, chbB, and chbC of the chb operon (formerly the cel (cellulose) operon). In the lichenan system, these subunits are expressed from licA, licB, and licC of the lic operon. The lic operon of Bacillus subtilis is required for the transport and degradation of oligomeric beta-glucosides, which are produced by extracellular enzymes on substrates such as lichenan or barley glucan. The lic operon is transcribed from a gammaA-dependent promoter and is inducible by lichenan, lichenan hydrolysate, and cellobiose. 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.

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.

5-83 5.55e-07

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.
