Localising individual atoms of tryptophan side chains in the metallo- β-lactamase IMP-1 by pseudocontact shifts from paramagnetic lanthanoid tags at multiple sites
{{output}}
The metallo-β-lactamase IMP-1 features a flexible loop near the active site that assumes different conformations in single crystal structures, which may assist in substrate binding and enzymatic activity. To probe the position of this loop, we labelled th... ...
