Figure 4. Crystal structures of Cl-Tyr157 CDO.

Figure 4

The omit Fo-Fc electron densities (green) of the WT CDO & mutants contoured at 3 σ (green) and 6 σ (purple), respectively. a, The active site of the Cl-Tyr157 CDO structure in the crosslinked and uncrosslinked forms in the absence of the substrate. b, The active site of the substrate-bound Cl-Tyr157 CDO structure in the crosslinked form. CYS represents the L-cysteine substrate bound at the nonheme iron center.
