Studies on structure of human erythrocyte phosphofructokinase.
Human erythrocyte phosphofructokinase has been purified to homogeneity and some of its physicochemical properties have been investigated. The enzyme exists in several polymeric states. At high protein concentrations (3 mglml), the predominant form of the enzyme shows a sedimentation coefficient of 57 S. In highly dilute solution (0.3 to 10 pg/ ml), the enzyme is in 12 S to 18 S forms as shown b...

15 صفحه اولThe interaction of phosphofructokinase with erythrocyte membranes.
The interaction of muscle phosphofructokinase with human erythrocyte ghost membranes was investigated. Scatchard analysis of the binding reveals only a single class of binding sites numbering approximately 4 x 10” sites/ghost with an association constant of 2 X lo7 M-‘. Maximum binding is observed below pH 6.8 and is complete within 30 min at 4”, 24”, and 37°C; binding is inhibited by high ioni...
متن کاملStudies on Phosphoglucomutase and Phosphofructokinase from Brain
It has recently been established that the activity of crystalline muscle phosphoglucomutase can be greatly stimulated by preincubation of the enzyme with a Mg++-imidazole complex. This observation has aroused interest in the physiological significance of such a system i n the possible cellular control of phosphoglucomutase activity. The present study constitutes, i n part, an investigation of t...
