Figure 6.
FIG. 6. Active site around the DCS- or LCS-bound PLP derivative. DCS-bound derivatives at sites A and B are shown in a and b, respectively. The LCS-bound derivatives at sites A and B are shown in c and d, respectively. The carbon atoms of the residues from each monomer are shown in orange and cyan. The carbon atoms of the residues from the PLP derivative, designated SCP, are shown in purple.
