FastRelax是Rosetta中优化结构的重要模块,可以用于消除晶体结构中的不合理构象,优化点突变设计的结构,以及比较多个不同结构的能量等。 在Rosetta力场下,FastRelax模块通过多次迭代进行氨基酸侧链重排以及能量最小化的计算来搜索给定三维结构的在局部能垒的最优构象。在每轮迭代中,程序脉动式地升高和降低范德华排斥力部分...

从能量变化浮动来说,repack的能量变化范围更宽,minimization相对较小。通常来说要对一个结构进行能量优化的话一般是组合了多轮的repack和minimizations,然后最简单最直接的应用就是FastRelax, FastRelax包含了多轮的packing和minimization,最终得到优化的结构。 7. PROTOCOL里packer和minmover的前后顺序不同会造成total sco...

Structure calculations were set up with automated Python scripts using CS-Rosetta67,68. We first used TALOS-N to determine psi and phi dihedral angles, and we used protein design sequences and assigned chemical shift values to pick fragments of amino acid lengths 3 and 9. We then used the ...

还有其他一些对称性感知的mover也可以使用。你可以在Rosetta Documentation中找到它们。这些包括FastRelax和FastDesign,它们经常被用于对称pose。 最后,在<PROTOCOLS>部分,我们布置了mover的顺序。首先,我们将设置对称性,然后重新打包,然后最小化: ...<PROTOCOLS><Addmover="add_symm"/><Addmover="symm_pack"/><Add...
