Molecular Modeling for Beginners by Gale Rhodes, Univ. Southern Maine, includes an introduction to DeepView, and a superb tutorial on homology modeling (look through the left index frame for the link to Homology 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. HM is the easiest tool to run in CAD, but it performs a complex set of functions. 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.

23 Oct 2020 Because homology modeling relies on a structural template, it is easier in detail the specific steps for multi-template homology modeling of 

Don't be afraid, you should be through this tutorial in less than 10 minutes. Homology Modelling. Homology modeling involves taking a known sequence with an unknown structure and mapping it against a known structure of one or several similar (homologous) proteins. It would be expected that two proteins of similar origin and function would have reasonable sstructural similarity.

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.

Homology modelling steps

In summary: homology modeling steps 1) Template recognition & initial alignment 2) Alignment correction 3) Backbone generation 4) Loop modeling 5) Side-chain modeling 6) Model optimization 7) Model validation 10. Homology models are unlikely to be useful in modeling ligand docking (drug design) unless the sequence identity with the template is >70%, and even then, less reliable than an empirical crystallographic or NMR structure.

Loop modeling Energy minimization Loop modeling Energy minimization Steps in homology modeling • Identify a sequence of interest. • Search database for homologs of known structure. • Align homologs with each other and with query. • Add structural homologs, if necessary. • Define SCRs and “Designated Loops”. Assign coordinates.
