In quantum mechanics calculations for the entire structure of big molecular system such as biomacromolecular system, the single point calculations for the initial structure obtained from classical molecular mechanics calculations and/or classical molecular dynamics calculations cannot converge or will give abnormal energies. For obtaining reliable results from quantum mechanics calculations such as fragment molecular orbital methods of entire molecular system, the initial structure must be prepared using geometrical optimization calculations via ONIOM methods. ONIOM Interface for Receptor can provide the best solution for the quantum mechanics calculations of the entire molecular system of which the precise initial structure is prepared from Docking Study with HyperChem and Homology Modeling Professional for HyperChem.

Homology Modeling Professional for HyperChem is the latest molecular modeling package.
The latest method on the basis of the energy calculations via HyperChem and Gaussian programs.
It can carry out the molecular modeling, functional analysis, and simulations of a big molecular system using comprehensively the ab-initio quantum chemistry calculations and the molecular dynamics simulations as well as the molecular mechanics calculations.
The program package can be used for performing the protein homology modeling in the presence or absence of the small molecules, water molecules, other biological molecules, metal atoms, and the small molecule covalently bound to the model under the vacuum or the various solvated conditions. The package supports the state-of-art technologies for modelings, simulations, and analyses.
The protein homology modeling can be performed using only three module programs to optimize the structure of the main chain, side chain, and whole molecule system. Since these module programs can automatically operate, the homology modeling can be precisely performed under the almost full automatic conditions.
Powered by Homology Modeling Professional for HyperChem THE IMPOSSIBLE BECOMES POSSIBLE.
New, High-Performance Software for Protein Modeling, Functional Analysis, and Simulation.
Homology Modeling Professional for HyperChem is the latest molecular modeling package which can carry out the molecular modeling, functional analysis, and simulations of a big molecular system using comprehensively the ab-initio quantum chemistry calculations and the molecular dynamics simulations as well as the molecular mechanics calculations. The program can control seamlessly both HyperChem and Gaussian packages and can be simultaneously fed back their calculation results to the big molecular system in the HyperChem graphical user interface. The whole molecular system can be operated in a quantum chemistry via the full-automatic ONIOM interface to Gaussian. All operations are fully automated in the GUI-based manner, and thus the program supports the logical molecular modeling, functional analysis, and simulations in the life science research such as the structure-based drug design, as well as an unexplored research. Moreover, this program package can cooperate with a protein- and ligand-flexible docking and screening program package bearing the next generation drug discovery technology, PIEFII technology. From the Revision B1, the protein modeling, functional analysis, and simulations can be performed in the level of figure of a literature or a demonstration using the full-automatic rendering and labeling functions.

Homology Modeling Professional for HyperChem Outline
Homology Modeling Professional for HyperChem is a package that consists of some module programs which are required for performing the protein modeling, functional analysis, and simulations using HyperChem which is well-known molecular modeling software in the world. The individual module programs in the package carry out new technologies. Therefore, by the fusion of these technologies to the HyperChem functions, the package serves as the latest structure-based drug design system in the drug discovery as well as serves as the latest protein modeling, functional analysis, and simulation systems.
Software Development for Researchers
Homology Modeling Professional for HyperChem is designed to reflect intuitive operation. That is, almost all of purposes can be performed only clicking the provided button in the individual module programs. Moreover, it is only necessary to operate a rotation of molecules in the HyperChem workspace, since several tools conferred from the package can automatically navigate the operations. For example, the program distinguishes between proteins, waters, and other molecules, and shows differences of these molecules. All module programs support the full-automatic rendering and labeling functions and thus the protein modeling, functional analysis, and simulations can be performed in the level of figure of a literature or a demonstration. The "Undo" function is available when the structure is modified. An objective part is automatically centralized in the HyperChem workspace. Thus, it is possible to make homology modeling of proteins without any knowledge for the HyperChem operations, although power users can carry out all functions of HyperChem.
Applicability for the Complicated Molecule System
Homology Modeling Professional for HyperChem covers almost all of the PDB structural data registered to date, since the package can deal with about 100,000 atoms (HyperChem 7.5 or later). The protein modeling as well as the protein functional analysis can be carried out under all conditions, where the molecule system can contain small molecules, metals, and polymers, etc. Moreover, the protein modeling can be performed using our new technology, even though the above molecules and atoms covalently bind to protein molecules. Their atom types are assigned automatically, and their atomic charges can be generated using many theoretical calculations. Otherwise, it can also give manually. Thus, the package can support the high-level, structure-based drug design such as the lead optimizations, since the package can analyze the detailed interactions between compounds such as seed and lead compounds and protein molecules such as the highly-precise protein models and the crystal structure optimized by this package.
The Most Powerful Computational Chemistry Environment
Homology Modeling Professional for HyperChem provides a powerful protein functional analysis environment, since this package supports all theoretical calculations integrated into HyperChem. The package can also use those supported in combinations of Mopac2000 and Mopac Interface for HyperChem and those supported by Q-Chem for Windows, if these programs are available. Moreover, the package can automatically reflect the electronic state of all molecules except for protein molecules to the corresponding molecules in the HyperChem workspace via Gaussian Interface for HyperChem. The whole molecular system in the HyperChem workspace can be operated in a quantum chemistry via ONIOM Interface for Receptor.
No preparation and editing are necessary for parameter files and PDB files. Of course, a detailed log file including the used parameters and the results are generated automatically. The individual module programs in the package carry out a file manager function. The early versions of HyperChem can be renewed as the latest protein modeling and functional analysis environment, since the package runs on HyperChem 5.x, 6.x, 7.x, and 8.0x.
Moreover, Homology Modeling Professional for HyperChem shows the powerful performance which is able to support logically an unexplored study such as the ligand recognition mechanism of receptor. Since this package runs on the Intel based Windows platforms, large advantage of both computational cost (computational speed) and user interface is expected in comparison with those of the corresponding system in the Unix platforms.
Reproducibility and Logical Molecular Modeling
Homology Modeling Professional for HyperChem can provide the reproducibility and logicalness of the models by performing molecular modeling on HyperChem consistently. As the results, the package enables large shortening of total operations, as well.
