资源简介:
Molecular Dynamics simulation results are given in the .xvg files. File names codify the system investigated: - The "VKEETPVd_" stands for the variables: Potential Energy (kJ/mol) Kinetic Energy (kJ/mol) Total Energy (kJ/mol) Conserved Energy (kJ/mol) Temperature (K) Pressure (bar) Volume (nm^3) Density (kg/m^3) - The uppercase letter stands for the amino acid in the mixture and it follows standard abbreviation. - "w" stands for the water, which is the solvent. - Next, there is a set of numbers, which specify the mole fraction composition. In this case, they are the digits after the decimal separator. - Last, the letters "a" or "g" were used to identify the force field used to model the amino acids. "a" stands for the OPLS-AA/M and "g" for the GROMOS 54A7. Example: VKEETPVd_Lw0010a.xvg contains the GROMACS' output data for NPT simulation of aqueous Leucine with 0.0010 mole fraction using OPLS-AA/M force field. We considered only the production data (5 to 10 ns). Standard Amino Acids Abbreviation: G = Glycine A = Alanine V = Valine L = Leucine I = Isoleucine P = Proline F = Phenylalanine Y = Tyrosine W = Tryptophan S = Serine T = Threonine C = Cysteine M = Methionine N = Asparagine Q = Glutamine D = Aspartic Acid (In this work, modeled in the form of Sodium salt) E = Glutamic Acid (In this work, modeled in the form of Sodium salt) K = Lysine (In this work, modeled in the form of Monohydrochloride salt) R = Arginine (In this work, modeled in the form of Monohydrochloride salt) H = Histidine EXCEPTIONS: For pure water simulations were simply named "water".

分子动力学(Molecular Dynamics)模拟结果存储于.xvg格式文件中。文件名对所研究的体系进行了编码,具体规则如下: - 前缀“VKEETPVd_”依次对应以下物理量:势能(kJ/mol)、动能(kJ/mol)、总能量(kJ/mol)、守恒能量(kJ/mol)、温度(K)、压强(bar)、体积(nm³)与密度(kg/m³)。 - 文件名中的大写字母代表混合体系中的氨基酸,采用标准氨基酸缩写规则。 - 字符“w”代表溶剂水。 - 紧随其后的一组数字用于指定摩尔分数组成,此处为小数点后的数位。 - 文件名末尾的“a”或“g”用于标识模拟氨基酸所用的力场:“a”代表OPLS-AA/M力场,“g”代表GROMOS 54A7力场。 示例:VKEETPVd_Lw0010a.xvg文件包含了采用OPLS-AA/M力场、对摩尔分数为0.0010的亮氨酸(Leucine)水溶液进行NPT模拟的GROMACS输出数据。本数据集仅选取了生产模拟阶段(5 ns至10 ns)的数据。 标准氨基酸缩写对照表如下: G = 甘氨酸(Glycine) A = 丙氨酸(Alanine) V = 缬氨酸(Valine) L = 亮氨酸(Leucine) I = 异亮氨酸(Isoleucine) P = 脯氨酸(Proline) F = 苯丙氨酸(Phenylalanine) Y = 酪氨酸(Tyrosine) W = 色氨酸(Tryptophan) S = 丝氨酸(Serine) T = 苏氨酸(Threonine) C = 半胱氨酸(Cysteine) M = 甲硫氨酸(Methionine) N = 天冬酰胺(Asparagine) Q = 谷氨酰胺(Glutamine) D = 天冬氨酸(Aspartic Acid,本研究中以钠盐形式建模) E = 谷氨酸(Glutamic Acid,本研究中以钠盐形式建模) K = 赖氨酸(Lysine,本研究中以一盐酸盐形式建模) R = 精氨酸(Arginine,本研究中以一盐酸盐形式建模) H = 组氨酸(Histidine) 例外情况:纯水模拟的文件直接命名为"water"。
