WebHow does ATP regulate the activity of PFK-1? ATP binds to the catalytic site as a substrate, increasing PFK-1 activity. ATP binds to the allosteric site as an activator, increasing PFK-1 activity. ATP binds to the allosteric site as an inhibitor, decreasing PFK-1 activity. WebPhosphofructokinase-1 (PDB ID: 3O8O) from Saccharomyces cerevisiae Created by: Mariam Yaktieen Phosphofructokinase-1 (PFK1) (PDB ID: 3O8O) is an allosteric multisubunit enzyme that falls under the Transferases Class (1). The proteins under this class catalyze phosphorylation reactions in a cell (9).
