Abstract
<p><b>(A)</b> The active site pocket of Alr<sub><i>Tt</i></sub> (PDB 4Y2W), phosphate group, L-Ala and key amino acids that involved in substrate binding are shown in sticks, the hydrogen bonding interactions are indicated. Same view of the active site pocket of other three bacteria alanine racemase in complex with substrates are shown in same profile: <b>(B)</b> the PLP-D-Ala complex of Alr<sub><i>Bst</i></sub> (PDB 1L6G), <b>(C)</b> PLP complex of Alr<sub><i>Cd</i></sub> (PDB 4LUS), <b>(D)</b> PLP and DLY complex of DadX<sub><i>pao</i></sub> (PDB 1RCQ).</p
