The NMR solution structure of a Pseudomonas metallothionein reveals a different binding capacity for ZnII and CdII ions that results in two novel metal-cluster topologies. Replacement of a non-coordinating residue by histidine decreases the kinetic lability of the cluster. All three structures reported show an identical protein fold.
