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.

3-96 1.79e-12

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.

2-52 1.28e-06

PTS_IIB_galactitol: subunit IIB of enzyme II (EII) of the galactitol-specific phosphoenolpyruvate:carbohydrate phosphotransferase system (PTS). In this system, EII is a galactitol-specific permease with two cytoplasmic domains (IIA and IIB) and a transmembrane channel IIC domain that are expressed on three distinct polypeptide chains, in contrast to other PTS sugar transporters. The three genes encoding these subunits (gatA, gatB, and gatC) comprise the gatCBA operon. Galactitol PTS permease takes up exogenous galactitol, releasing the phosphate ester into the cytoplasm in preparation for oxidation and further metabolism via a modified glycolytic pathway called the tagatose-6-phosphate glycolytic pathway. 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 galactitol, chitobiose/lichenan, ascorbate, lactose, mannitol, fructose, and a sensory system with similarity to the bacterial bgl system.

PTS_IIB_lactose: subunit IIB of enzyme II (EII) of the lactose-specific phosphoenolpyruvate:carbohydrate phosphotransferase system (PTS) found in Firmicutes as well as Actinobacteria. In this system, EII is a lactose-specific permease with two cytoplasmic domains (IIA and IIB) and a transmembrane channel IIC domain. The IIC and IIB domains are expressed as a single protein from the lac operon. 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 lactose, chitobiose/lichenan, ascorbate, galactitol, mannitol, fructose, and a sensory system with similarity to the bacterial bgl system.

3-83 5.16e-03

PTS_IIB_ascorbate: subunit IIB of enzyme II (EII) of the L-ascorbate-specific phosphoenolpyruvate:carbohydrate phosphotransferase system (PTS). In this system, EII is an L-ascorbate-specific permease with two cytoplasmic subunits (IIA and IIB) and a transmembrane channel IIC subunit. Subunits IIA, IIB, and IIC are encoded by the sgaA, sgaB, and sgaT genes of the E. coli sgaTBA operon. In some bacteria, the IIB (SgaB) domain is fused C-terminal to the IIA (SgaT) 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 ascorbate, chitobiose/lichenan, lactose, galactitol, mannitol, fructose, and a sensory system with similarity to the bacterial bgl system.
