Abstract
Establishing the binding topology of structural zinc ions in proteins is an essential part of their structure determination by NMR spectroscopy. Using (113) Cd NMR experiments with (113) Cd-substituted samples is a useful approach but has previously been limited mainly to very small protein domains. Here we used (113) Cd NMR spectroscopy during structure determination of Bud31p, a 157-residue yeast protein containing an unusual Zn3 Cys9 cluster, demonstrating that recent hardware developments make this approach feasible for significantly larger systems.
