Figure 3
CASDC active site. Pyridoxal 5′-phosphate is shown with yellow carbons. (a) ClCASDC. Chain A is shown with grey carbons. Chain B is shown with blue carbons. Asp276 originates from α9, the specificity helix. Cys306 has 70% occupancy in the `up' position relative to the figure orientation. Electron density is displayed as a 2mFo − DFc map contoured at 1.5σ. (b) CjCASDC (PDB entry 3n29). |
