A prominent surface loop links the first two beta strands of the lipoyl domain (E2plip) from the pyruvate dehydrogenase multienzyme complex of Escherichia coli. We show here that shortening this loop by two residues generates a protein that populates two structurally distinct stable conformers: an active, native-like monomer (HM) and a functionally compromised misfolded dimer (LM) ...
