Figure 3

Overlay of the active site residues of the refined homology model with the crystal structures. Active site residues of the homology model of the complete monomer refined by 20 ns of molecular dynamics in a NPT ensemble, are shown in an overlay with PDB entry: 1c7s: Serratia marcenscens (yellow), 1jak: Streptomyces plicates (green), 1now: Homo sapiens (magenta). In the human structure the tryptophane residue is not conserved and thus missing in the structure, and in the Serratia marcenens structure the aspartic acid is mutated to alanine. The overlay shows clearly a spatial alignment with our calculated and refined structure.
