Cabrera Paucar, Ricardo; Guixé Leguía, Victoria Cristina; Alfaro, Jennifer; Rodríguez, Patricio H.; Babul Cattán, Jorge (2002)Binding of MgATPto the allosteric site of phosphofructokinase-2 promotes a dimer to tetramer conversion. In the presence of Fru-6-Pthe enzyme remains as a dimer. Limited proteolysis in the presence of MgATPcompletely ...

Cabrera Paucar, Ricardo; Babul Cattán, Jorge; Guixé Leguía, Victoria Cristina (ELSEVIER SCIENCE INC, 2010-06-25)Phosphofructokinase-2 (Pfk-2) belongs to the ribokinase family and catalyzes the ATP-dependent phosphorylation of fructose-6-phosphate, showing allosteric inhibition by a second ATP molecule. Several structures have been ...
