Figure 7
Stereoview into the putative acceptor-binding site. The Fo − Fc OMIT difference density in the active site is shown as a green mesh contoured at 2.5σ. The resulting density after refinement with dummy water atoms is shown as a blue mesh contoured at 1.0σ. Anti-bumping restraints were omitted to allow `covalent bonding distances' between the dummy atoms. The residues which form the putative cavity and might interact with the acceptor are shown as sticks and are labelled accordingly. The cofactor AcCoA shown in stick representation was positioned according to the overlay with NATA (PDB entry 4kvx
). |
