Figure 4
Structure of C. difficile alanine racemase. (a) Monomer of C. difficile alanine racemase. Ribbon diagram with α-helices in orange and β-strands in green; the PLP cofactor bound to Lys39 is shown as magenta sticks. (b) Dimer of CdAlr_K271T. One monomer is shown in blue ribbon and the second is depicted as a green ribbon and surface. The PLP adduct, Llp39, is shown as magenta sticks. (c) Superposed ribbon structures of monomers of CdAlr_PLP (blue), CdAlr_K271T (grey) and CdAlr_cycloserine (orange). Llp39 is shown as magenta sticks and DCS is shown as blue sticks.
