Incubation of this enzyme preparation with [γ-32P]ATP and Mn2+ or Mg2+ gave a phosphoprotein of molecular mass 58000 which corresponded to hexokinase PII. d-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. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-134-9-2493
