Comparative Protein Structure Modeling Using MODELLER
Comparative protein structure modeling predicts the three dimensional structure of a given protein sequence (target) based primarily on its alignment to one or more proteins of known structure (templates) The prediction process consists of fold assignment, target template alignment, model building, and model evaluation. This unit describes how to calculate comparative models using the program MODELLER and how to use the ModBase database of such models, and discusses all four steps of comparative modeling, frequently observed errors, and some applications. Modeling lactate dehydrogenase from Trichomonas vaginalis (TvLDH) is described as an example. The download and installation of the MODELLER software is also described.
