Figure 7
Surface representations of the substrate-binding site with bound Trp (orange C atoms) and 5-Br-Trp (green C atoms). The representations in (a) and (b) are rotated by 180°. The hydrophobic pocket surrounding the bromine is mostly formed by residues from the insertion in the NADP-binding domain (Leu183, Met217, Val220, Pro250 and Leu254) and by Phe372 from the FAD-binding domain. |
