| 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 a phospho-carrier protein of low molecular mass that has been
phosphorylated by EC 2.7.3.9.
- Enzyme II, on the other hand, is specific for a particular substrate,
although in some cases alternative substrates can be transported with
lower efficiency.
- 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.
