DockoMatic 2.0 is a powerful open source software program (downloadable from sourceforge.net) that simplifies the exploration of computational biochemistry. This manuscript describes a practical tutorial for use in the undergraduate curriculum that introduces students to macromolecular structure creation, ligand binding calculations, and visualization of docking results. A student procedure is provided that illustrates use of DockoMatic to create a homology model for the amino propeptide region (223 amino acids with two disulfide bonds) of collagen α1 (XI), followed by molecular docking of the commercial drug Arixtra® to the homology model of the amino propeptide domain of collagen α1 (XI), and finally, analysis of the results of the docking experiment. The activities and supplemental materials described are intended to educate students in the use of computational tools to create and investigate homology models for other systems of interest and to train students to be proficient with molecular docking and analyzing results. The tutorial also serves as a foundation for investigators seeking to explore the viability of using computational biochemistry to study their receptor-ligand binding motifs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
