Activating Compound
| EC Number | Activating Compound | Comment | Organism | Structure |
|---|---|---|---|---|
| 7.5.2.1 | maltose-binding protein | required by wild-type strain, mutant strain does not require maltose-binding protein for transport. The major function of the maltose-binding protein is to send a transmembrane signal, in the presence of ligands, to the ATPase subunits on the inner side of the membrane. In addition it performs a special function in the translocation of the larger ligands, maltodextrins, perhaps by aligning them from entry into the channel | Escherichia coli |
