FunFam 140190: Cellobiose-specific phosphotransferase enzyme IIB ...

There are 2 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

    Protein-N(pi)-phosphohistidine--D-cellobiose phosphotransferase. [EC: 2.7.1.205]
    [Protein]-N(pi)-phospho-L-histidine + D-cellobiose(Side 1) = [protein]-L- histidine + D-cellobiose 6'-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 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.
