Engineering di-iron enzymes
A dramatic switch of reactivity — from hydroquinone oxidation to N-hydroxylation — can be achieved through the rational engineering of a de novo-designed di-iron protein. Four specific amino-acid mutations spread...

Incorporation of the red copper nitrosocyanin binding loop into blue copper azurin
Loop-directed mutagenesis was applied to the blue copper protein azurin to replace its copper binding loop with that from the red copper protein nitrosocyanin. A ten amino acid long loop that provides three of...

Models of noncoupled dinuclear copper centers in azurin
The successful modeling of metalloproteins is an important step in understanding their structure and function. Toward this goal, models of the noncoupled copper centers found in the enzymes peptidyl α-hydroxyl...

Probing Mercury Complex Speciation with Multinuclear NMR
Investigation of the solution-state coordination chemistry of mercury presents unique challenges. Multinuclear NMR methods are particularly appropriate for the characterization of mercury complexes in so...
