| - La proteína-N(pi)-fosfohistidina azúcar fosfotransferasa (EIIB) (EC 2.7.1.69) es una enzima que cataliza la reacción: Proteína EIIB N(pi)-fosfo-L-histidina/cisteína + azúcar proteína EIIB + azúcar fosfato El sustrato proteico es una proteína fosfotransportadora de bajo peso molecular (9,5 kDa). La proteína sustrato es fosforilada en una reacción catalizada por la enzima fosfoenolpiruvato-proteína kinasa (EC 2.7.3.9) y actúa como donante del grupo fosfato. La EIIB translocaliza el azúcar que fosforila al interior de la célula. Las aldohexosas, sus glicósidos y sus alditoles son fosforilados en el oxígeno 6 (O-6). La fructosa y la sorbosa en O-1. La glicerina y los disacáridos actúan también como sustratos. (es)
- In enzymology, a protein-Npi-phosphohistidine-sugar phosphotransferase (EC 2.7.1.69) is an enzyme that catalyzes the chemical reaction protein Npi-phospho-L-histidine + sugar protein histidine + sugar phosphate Thus, the two substrates of this enzyme are and sugar, whereas its two products are and sugar phosphate. This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups (phosphotransferases) with an alcohol group as acceptor. The systematic name of this enzyme class is protein-Npi-phosphohistidine:sugar Npi-phosphotransferase. Other names in common use include glucose permease, PTS permease, phosphotransferase, phosphohistidinoprotein-hexose, enzyme IIl4ac, gene glC proteins, gene bglC RNA formation factors, PEP-dependent phosphotransferase enzyme II, PEP-sugar phosphotransferase enzyme II, phosphoenolpyruvate-sugar phosphotransferase enzyme II, phosphohistidinoprotein-hexose phosphotransferase, phosphohistidinoprotein-hexose phosphoribosyltransferase, phosphoprotein factor-hexose phosophotransferase, protein, specific or class, gene bglC, ribonucleic acid formation factor, gene glC, sucrose phosphotransferase system II, and protein-Npi-phosphohistidine:sugar N-pros-phosphotransferase. This enzyme participates in 7 metabolic pathways: , fructose and mannose metabolism, galactose metabolism, , , aminosugars metabolism, and . (en)
