Heteronuclear NOE data showing fast-timescale motions of apo and ertapenem-bound IMP-13. Heteronuclear NOE data for the backbone amides and tryptophan indole NεHε measured at 600 MHz (1H frequency) and 25°C for both the apo and ertapenem-bound forms. The loop 1 region is marked with a red rectangle. Residues above residue 224 were removed from the plot, as all showed negative heteronuclear NOEs in both the apo and ertapenem-bound forms.
