Characterization of chromate reductase of Pseudomonas putida

A soluble chromate reductase has been purfied to homogeneity n Dr. Matin's Lab at Stanford University. It is very likely that this enzyme reduces toxic Cr(V1) to nontoxic Cr(III). to absolutely confirm this, Electron Spin Resonance measurements are needed. This is a request for Drs. Jim Amonette and Ravi Kukkadupu, who are experts in this technology, to conduct the required experiments.
