Docking with Surflex-Dock The crystal structure of β- N -acetyl- d -hexosaminidase (OfHex1, 2.1 Å, 3NSN.
The selected lead-like compounds were subjected to a multistep docking-based simulation with the crystal structure of OfHex1 (3NSN.
The average 3D-structures of complexes were compared with the X-ray crystallographic structure of 3NSN ( Figure 4A–F ).
Top scoring compounds with poor binding mode inside the active site of the protein (pdb id: 3NSN) are indicated with arrows.

The PDB files of OfHex1 (3NSN), SmChb (1QBB) and SpHex (1HP5) were selected as inputted structures.
Results Structure Comparisons between BGlu1-cellotetraose and OfHex1-TMG-Chitotriomycin Structural comparisons between BGlu1-cellotetraose (PDB accession number: 3F5J)  and OfHex1-TMG-chitotriomycin (PDB accession number: 3NSN)  were performed to reveal structural differences and similarities.
OfHex1 (PDB accession number: 3NSN) and two bacterial β-N-acetyl-D-hexosaminidases, SmChb from S. marcescens (PDB accession number: 1QBB)  and SpHex from S. plicatus (PDB accession number: 1HP5)  , were selected as input structures.
Determination and Refinement of Structures The structure of mutant OfHex1 (E328A)-TMG-chitotriomycin complex was solved by molecular replacement with Molrep  using the structure of OfHex1-TMG-chitotriomycin complex (PDB accession number: 3NSN) as the search model.
A sperm-plasma ?-N-acetyl-D-hexosaminidase interacting with a Chitinolytic ?-N-Acetyl-D-hexosaminidase in insect molting fluid.

The structure model of the catalytic domain of OfHex3 was built using the catalytic domain of OfHex1 (PDB ID: 3NSN) as a template and was validated using PROCHECK (89.8% of the residues were in the mo... t favored regions) and Verify_3D (93.4% of the residues had an average three- to one-dimensional score >0.2).
