Figure 4
Detailed active-site structures of S. aureus DltA and B. cereus DltA. (a) Close-up view of the active site of S. aureus DltA (chain A). The bound Mg2+ ion is shown as a purple sphere. The ATP molecule and the key residues engaged in the hydrogen-bonding network are shown as stick models. Residues from the N- and C-lobes are colored orange and blue, respectively. (b) Left: close-up view of the active site of ATP- and Mg2+-complexed B. cereus DltA (PDB entry 3fcc). Residues engaged in the hydrogen-bonding network are shown as stick models and colored white. Right: close-up view of the active site of D-alanine-adenylate-complexed B. cereus DltA (PDB entry 3dhv). Residues engaged in the hydrogen-bonding network are shown as stick models and colored cyan. |
