Fig. 4. Structures of Grxs non-functional with PAPS reductase with altered active site geometry. Secondary structure representations of (A) T4 Grx and (B) E. coli Grx2. The loops and domain protruding from the area corresponding to the contact surface in Trx1 are marked. The pictures were computed using the DeepView/Swiss-PDB Viewer 4.1 with PDB accession numbers ; 1de2 (T4)36 and ; 1g7o (Grx2).32.
