The influence of insulin and glucagon on the interactions between glycolytic enzymes and cellular structure.

The influence of insulin and glucagon on the release of glycolytic enzyme activities and actin from cultured pig kidney cells treated with digitonin has been studied. Both insulin and glucagon reduced the release of all glycolytic enzymes except for phosphofructokinase, and concurrently reduced the release of actin. These data have been discussed in relation to their contribution to knowledge of the interactions between glycolytic enzymes and actin filaments of the cytoskeleton, and to the influence of hormones on these interactions.
