Figure 4
Stereo diagram showing the superimposition of the structures of AtGRXcp (orange) with (a) E. coli Grx4 (grey; PDB code 1yka ) and human Grx2 (cyan; PDB ID 2fls ) or (b) poplar GrxC1 dimer (grey; PDB code 2e7p ) in which two AtGRXcp molecules are superimposed on the GrxC1 dimer. The GSH in human Grx2 and GSH and the [2Fe–2S] cluster in poplar GrxC1 are shown as ball-and-stick models. |
