The Novikoff ascites tumor phosphofructokinase showed a lag in the onset of inhibition by adenosine triphosphate or citrate. Under identical assay conditions, Ehrlich ascites tumor P-fructokinase and the rabbit muscle enzyme were immediately inhibited by ATP. Advantage was taken of this lag period by first incubating the enzyme with ATP for 2 min before the assay of enzyme activity. After the f...

Antibodies directed against the enzyme glutamic acid decarboxylase (GAD) are believed to be the main cause of destruction of pancreatic islet cells in type I (insulin dependent) diabetes mellitus. The enzyme was found both in the brain and pancreatic beta cells. Although similarities in identity of GAD in human and rat brain have been demonstrated, little is known about the interaction betw...
