Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe structure of the complex of urease, a Ni-containing metalloenzyme, with boric acid was determined at 2.10 A resolution.
