Figure 4
Stereoview of the PGA-A–LmCS complex overlaid with a peptide–AtOAS-TL complex. The LmCS structure is shown as in Fig. 3, with the locations of α7 and the TKY motif indicated. The model of the AtOAS-TL–peptide complex (PDB entry 2isq
; Francois et al., 2006) is coloured purple. The peptide sequence corresponds to that of the C-terminal residues of SAT. Hydrogen-bonding interactions are depicted as dashed lines coloured according to the structure in which they occur. |
