Elucidation of the mechanisms of inter-domain coupling in the monomeric state of Enzyme I by high-pressure NMR

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-
