Abstrakt: |
A rapid, high-yield procedure has been developed for the purification of HPr from the Escherichia coli phosphoenolpyruvate dependent phosphotransferase system. During this procedure, the protein copurifies with a 2500-dalton homopolysaccharide which we have identified as alpha 1-6 glucan. The results of steady-state kinetic measurements of the phosphotransferase activity demonstrate that the polysaccharide works as an activator of the phosphotransferase system probably at the level of the HPr:P-E1 complex or the P-HPr:E11 complex. |
