Substrate entryway. (a) A stereoview of the substrate entryway of CdAlrK271T superposed with CdAlrcycloserine. (b) The same stereoview of the substrate entryway of CdAlrK271T superposed with that of EcAlr. In both figures residues from one monomer of CdAlrK271T are shown in pink, while residues from the second monomer are shown in blue and Lys271 from CdAlrWT is shown in yellow. Corresponding residues in EcAlr are colored green and aquamarine, respectively. The transparent surface and ribbon diagram shown are of CdAlrK271T. |
