Formally this means that at this point [alpha] = 1, and no allosteric feedback between the substrate binding sites should occur if the substrate is characterized by the [K.
Most likely this means that the binding of substrate molecules with two subunits of L-PK triggers off the conformational transition that changes the substrate binding sites on the two remaining subunits.
Eidogen's comparative analysis of the two protease structures revealed significant similarities in the substrate binding sites.
