Green Fluorescent Protein-Focused Bioinformatics Laboratory Experiment Suitable for Undergraduates in Biochemistry Courses

Abstract

An introductory bioinformatics laboratory experiment focused on protein analysis has been developed that is suitable for undergraduate students in introductory biochemistry courses. The laboratory experiment is designed to be potentially used as a “stand-alone” activity in which students are introduced to basic bioinformatics tools and applications after they have covered fundamental aspects concerning the structure and function of proteins within a class. This laboratory experiment explores three different protein bioinformatics tasks using freeware programs available on the National Center for Biotechnology Information Web site. Students first determine the identity of a protein, and its close homologues, to which they have been given an amino acid sequence using the BLASTP search tool. They then perform a multiple alignment of this protein with a given selection of proteins using the COBALT program and analyze and interpret the alignment results to predict the most promising sites for mutagenesis.
