Crystal structure of Xcc4156. (a) Dimer in the crystal of Xcc4156 (PDB entry 6y1w). The structurally conserved part between different FDHs (`box') is shown in dark blue and the structurally variable `pyramid' is shown in light blue. (b) Monomer of Xcc4156 (chain A). The FAD-binding loop in the `box' subdomain and a loop at the substrate-binding site at the interface between the `box' and the `pyramid' subdomains are highlighted. The inferred FAD-binding and substrate-binding sites (deduced from their respective positions in Trp halogenases) are marked as green ovals. |
