Below is the original summary to fill this mandatory field PROJECT SUMMARY/ABSTRACT Through the development and maintenance over the past 13 years, CHARMM-GUI (http://www.charmm- gui.org) has become an essential web-based resource for the interactive construction of complex biomolecular simulation systems and the preparation of their inputs with well-established and reproducible simulation protocols for state-of-the-art molecular simulations using widely used programs, such as CHARMM, NAMD, GROMACS, AMBER, GENESIS, TINKER, LAMMPS, Desmond, and OpenMM. CHARMM-GUI has also significantly reduced the learning curve that prevents non-experts (e.g., experimentalists) from utilizing modeling and simulation to study their systems. In this application, following requests from CHARMM-GUI users and broad MD simulation package developers, three specific aims are proposed to extend the functionality of CHARMM-GUI to support a broader range of modeling and simulation community with more diverse force field selection and advanced techniques. Specifically, AIM1 is to support a more complete list of additive and polarizable force fields for all- and united-atom simulations. AIM 2 is to develop QM/MM Interfacer for QM and QM/MM calculations. Finally, AIM 3 will extend the functionality of CHARMM-GUI with non- CHARMM implicit solvent models, SILCS-based simulations (Site Identification by Ligand Competitive Saturation), ligand binding free energy calculations, constant pH simulations, replica-exchange simulations, ion transport simulations, targeted/steered simulations, and path sampling. The successful completion of the proposed project is expected to provide an effective one-stop online resource for biomedical research community to carry out innovative and novel biomolecular modeling and simulation research for the prevention and treatment of human disease.

以下是填写此强制性字段的原始摘要 项目摘要/摘要 通过过去13年的开发和维护，Charmm-Gui（http：//www.charmm-- gui.org）已成为基于网络的基于基于网络的基本资源，用于复杂生物分子的互动结构 模拟系统及其投入的准备，并建立了良好且可重复的模拟 使用广泛使用的程序，例如Charmm，NAMD， Gromacs，Amber，Genesis，Tinker，Lammps，Desmond和OpenMM。 charmm-gui也有 显着降低了阻止非专家（例如，实验者）的学习曲线 建模和模拟以研究其系统。在此应用程序中，遵循Charmm-Gui的请求 用户和广泛的MD仿真软件包开发人员，提出了三个特定目标来扩展 Charmm-GUI的功能，以支持更广泛的建模和模拟社区 多样化的力场选择和高级技术。具体来说，AIM1是支持更完整的列表 用于全部和联合原子模拟的可添加和极化的力场。 AIM 2是开发QM/mm Interfacer 用于QM和QM/MM计算。最后，AIM 3将扩展Charmm-GUI的功能 CHARMM隐式溶剂模型，基于SILCS的模拟（配体竞争性识别现场识别 饱和度），配体结合能量计算，恒定pH模拟，复制 - 交换模拟， 离子传输模拟，靶向/转向模拟和路径采样。成功完成 预计拟议的项目将为生物医学研究提供有效的一站式在线资源 为预防进行创新和新颖的生物分子建模和模拟研究的社区 和人类疾病的治疗。
