Erratum

In the Research Artide ``Atomic structure of adenosine deaminase complexed with a transition-state analog: Understanding catalysis and immunodeficiency mutations'' by David K. Wilson et al. (31 May, p. 1278), figure 3D on page 1281 was inadvertently omitted. The figure and a corrected caption are printed below.

(D) Schematic diagram of the interaction between ADA and HDPR. Numbers near dashed lines indicate distances (in angstroms) between refined nonhydrogen atoms. As discussed in the text, Glu217 and Asp296 are likely to have pKa values greater than normal, His238 and Asp295 are likely to be in the ionized or charged species, and His17 (a zinc ligand) is neutral.
