Figure 5From: The crystal structure of alanine racemase from Streptococcus pneumoniae, a target for structure-based drug designSchematic diagram of polar interactions around PLP in the active site of alanine racemase from S. pneumoniae. For clarity, interactions with water molecules have not been included. Primed numbers denote residues from the second monomer. This figure was drawn after LeMagueres et al. [32].Back to article page
