The first step in homology modeling is to discover a template with high sequence similarity to our unknown protein, which has a known structure. Advanced Modeling. Model a sequence based on multiple templates and bound to a ligand. This exercise introduces the use of multiple templates, ligands and loop refinement in the process of model building with MODELLER. Iterative Modeling. Increase the accuracy of the modeling exercise by iterating the 4 step process.

You can run HM by inputting a sequence and come back later to get your structures. Homology modeling cannot be used to predict structures which have less than 30 % similarity. In rare cases, less than 20 % is also selected. Homology modelling is multi step process which includes sequence alignment, structural modification, database searches, energy minimization and structure evaluation to generate a structure.

So, a thorough understanding of all steps of the process (from template detection, via alignment, modelling, and model optimization, to the final validation) is required.

The overall homology modeling procedure consists of six steps. The first step is template selection, which involves the identification of homologous sequences in the protein structure database to be used as templates for modeling. The homology modeling procedure can be broken down into four sequential steps: template selection, target-template alignment, model construction, and model assessment.

The overall homology modeling procedure consists of six steps. The first step is template selection, which involves the identification of homologous sequences in the protein structure database to be used as templates for modeling.
This is the best starting place for beginners who want to learn about homology modeling. Steps in homology modelling/template-based modeling: Template identification, modeling & model quality Outlined below is a diagram and step-by-step descriptions of how Homology Modeling (HM) runs.
The first step is template Uses of Steps in model production The homology modeling procedure can be broken down into four sequential steps: template selection, target-template alignment, model construction, and model assessment. In the first step of model building, distance and dihedral angle restraints on the target sequence are derived from its alignment with template 3-D structures. The form of these restraints was obtained from a statistical analysis of the relationships between similar protein structures. So, a thorough understanding of all steps of the process (from template detection, via alignment, modelling, and model optimization, to the final validation) is required. And that is why this course exists.
