title: Particulate' hexokinase activity in rat intestine. The comparative contributions of mitochondria and brush-border membranes.
abstract: The activity of hexokinase was examined in brush-border membranes purified from rat intestine. Compared with homogenates, purified membranes exhibited a 20-fold increase in sucrase specific activity and a 15-fold decrease in hexokinase specific activity, which argues against the structural localization of hexokinase within the brush-border membrane.
