The catalytic cycle of Enzyme I (EI), a phosphotransferase enzyme responsible for converting phosphoenolpyruvate (PEP) into pyruvate, is characterized by a series of local and global conformational rearrangements. This multistep process includes a monomer-to-dimer transition, followed by an open-to-closed rearrangement of the dimeric complex upon PEP binding. In the present study, we investigate the thermodynamics of EI dimerization using a range of high-pressure solution NMR techniques...
