Modeller- Uses & Applications

Modeller is a standalone tool for homology modeling or comparative modeling of proteins 3D structures [1-4]. In this article, we are discussing its different uses and applications in bioinformatics.

Modeller predicts protein 3D structure by satisfying the spatial restraints. It is capable of performing some additional tasks as well. Some of the main uses and applications of Modeller are mentioned below:

  • Predicts protein 3D structure via homology or comparative modeling.
  • It automatically generates a protein structure containing all non-Hydrogen atoms by the satisfaction of spatial restraints.
  • It helps in the comparison of protein structures by aligning multiple structures together.
  • Modeller models loops in protein structure de novo.
  • It optimizes various models with respect to a flexibly defined objective function.
  • It can also search in sequence databases.
  • Performs clustering.
  • It can be used for different types of protein structure modeling including basic, advanced, iterative, difficult, and modeling with cryo-EM data.
