生信漫谈如何绘制蛋白序列的二级结构可视化图
大家经常在文献中看到非常漂亮的多序列比对图，上面标注了各种蛋白二级结构的信息，现在小白将目前见过的最好看的序列比对图和蛋白二级结构的组合图的作图方法作分享，希望对大家的科研工作有所帮助，效果图如下：

PQNTRAYDSSPHHFNWSL在用该网站之前需要把序列进行比对，用MEGA7就能完成，把第一条序列用蛋白同源建模
https://swissmodel.expasy.org/得到建模结果选择最佳的模型，下载PDB文件
现在进入ESPript / ENDscript网站，上传对应文件，采用初级 的默认功能进行图片可视化，再点击页面顶部的SUBMIT按钮即可。
这是以第一条蛋白序列作为模型构建的PDB文件，序列跟其他的蛋白序列差异比较大，建议选择同源性高的序列进行可视化，效果会更好。
