EXTENSION OF GLYCAM FORCE FIELD PARAMETERS TO ENABLE MODELING OF NUCLEIC ACIDS

这个子项目是利用资源的许多研究子项目之一。 由NIH/NCRR资助的中心拨款提供。对子项目的主要支持 子项目的首席调查员可能是由其他来源提供的， 包括美国国立卫生研究院的其他来源。为子项目列出的总成本可能 表示该子项目使用的中心基础设施的估计数量， 不是由NCRR赠款提供给次级项目或次级项目工作人员的直接资金。 琥珀力场已被广泛用于模拟核酸聚合物(DNA，RNA)，主要使用由Cheatham博士开发的参数。由于我们的GLYCAM参数能够准确地模拟碳水化合物环，他要求我们将参数扩展到核酸。这是一个重大项目，但有可能克服琥珀参数中一些长期存在的弱点。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. The AMBER force field has been widely used for simulating nucleic acid polymers (DNA, RNA) employing the parameters developed principally by Dr. Cheatham. Because of the ability of our GLYCAM parameters to accurately model carbohydrate rings, he has asked us to extend our parameters to nucleic acids. This is a major project, but has the potential to overcome some long-standing weaknesses in the AMBER parameters.
