Temperature effects on the kinetic properties of phosphofructokinase(PFK) purified from skeletal muscle of the golden-mantled ground squirrel,Spermophilus lateralis, were examined at 37 C and 5C, values character-istic of body temperatures in euthermia vs. hibernation. The enzymeshowed reduced sensitivity to all activators at 5C, theKa values forAMP, ADP, NH4+and F2,6P2 were 3–11-fold higher at 5C than at37C. Inhibition by citrate was not affected whereas phosphoenolpyruvate,ATP and urea became more potent inhibitors at low temperature. ...
