title: The phosphoenolpyruvate : methyl-alpha-D-glucoside phosphotransferase system in Bacillus subtilis Marburg 168 : purification and identification of the phosphocarrier protein (HPr).
abstract: The phosphocarrier protein (HPr) of the phosphoenol pyruvate : alpha-methyl-D-glucoside-phosphotransferase system (PTS) has been purified from Bacillus subtilis Marburg 168. The molecular weight is about 8300. HPr contains 1 histidine residue. Phophoenzyme I appears to be an intermediate in the initial phosphoryl transfer from phosphoenolpyruvate (PEP) to HPr. Phospho-HPr is isolated and characterized as a component of the complete system.
