|Fructose PTS permease.|
|[Protein]-N(pi)-phospho-L-histidine + D-fructose(Side 1) <=> [protein]-L-histidine + D-fructose 1-phosphate(Side 2)|
- 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 22.214.171.124.
- The enzyme from the bacterium Escherichia coli is an exception, since
it is phosphorylated directly by EC 126.96.36.199.
- The reaction involves a successive transfer of the phosphate group to
several amino acids within the enzyme before the final transfer to
- Formerly EC 188.8.131.52.
