Abstract
The binding of aldolase, glyceraldehyde-3-phosphate dehydrogenase and pyruvate kinase in fetal calf brain homogenates and extracts has been investigated at both 0° and 37°C under high ionic strength conditions. The results demonstrate far greater enzyme binding at 37°C than at 0°C, which correlates with an increased sedimentation of cytoskeletal actin at the higher temperature. A dependence of enzyme sedimentation on the presence of polymerised actin was also demonstrated, and this indicates that cytoskeletal actin is a major adsorbent of glycolytic enzymes in this non-muscle tissue.
