Abstract

Autophosphorylation of hexokinase PII was studied using an enzyme purified from Incubation of this enzyme preparation with [-P]ATP and Mn or Mg gave a phosphoprotein of molecular mass 58000 which corresponded to hexokinase PII. -Xylose stimulated autophosphorylation of hexokinase PII. Dilution of hexokinase PII over a 10-fold concentration range did not change the specific activity of hexokinase PII autophosphorylation suggesting that it may occur by an intramolecular mechanism.
