Sugar Transport by the Bacterial Phosphotransferase System

  title={Sugar Transport by the Bacterial Phosphotransferase System},
  author={Myun and K. and Han and Saul and Roseman},
Enzyme I (EI), the first protein of the bacterial phosphotransferase system (PTS), exists in a monomer/dimer (M/D) equilibrium. We have proposed that the two species are functionally different and that their interconversion may regulate sugar transport via the PTS. The C-terminal Cys of Escherichia coli E1 was reacted with pyrene maleimide (Han, M. K., Roseman, S., and Brand, L. (1990) J. Biol. Chem. 265,1985-1995), and the pyrene conjugate used to characterize the M/D equilibrium by… CONTINUE READING
