(a) Circular-dichroism spectrum of KpUreF in the absence (black squares) and the presence (light blue circles) of Ni2+ ions. (b) Analytical ultracentrifugation profile of KpUreF showing a single peak at ∼45 kDa corresponding to the molecular mass of a dimer. A representative SDS–PAGE gel (stained with Coomassie Blue) is shown in the inset. |
