ENZYME entry: EC 2.7.1.202

Accepted Name

protein-N(pi)-phosphohistidine--D-fructose phosphotransferase

Alternative Name(s)

fructose PTS permease

Reaction catalysed

D-fructose(out) + N(pros)-phospho-L-histidyl-[protein] = D-fructose 1-phosphate(in) + L-histidyl-[protein]

Comment(s)

This enzyme is a component (known as enzyme II) of a phosphoenolpyruvate (PEP)-dependent, sugar transporting phosphotransferase system (PTS).
The system, which is found only in prokaryotes, simultaneously transports its substrate from the periplasm or extracellular space into the cytoplasm and phosphorylates it.
The phosphate donor, which is shared among the different systems, is usually a phospho-carrier protein of low molecular mass that has been phosphorylated by EC 2.7.3.9.
The enzyme from the bacterium Escherichia coli is an exception, since it is phosphorylated directly by EC 2.7.3.9.
The reaction involves a successive transfer of the phosphate group to several amino acids within the enzyme before the final transfer to the substrate.
Formerly EC 2.7.1.69.
