Introductory bioinformatics exercises utilizing hemoglobin and chymotrypsin to reinforce the protein...

Area of Science:

• Biochemistry
• Bioinformatics
• Computational Biology

Background:

• Undergraduate biochemistry curricula often lack hands-on bioinformatics training.
• Students possess foundational knowledge of proteins like hemoglobin and chymotrypsin.
• Understanding the link between protein sequence, 3D structure, and biological function is crucial.

Purpose of the Study:

• To develop and implement two computer laboratory exercises for an upper-level undergraduate biochemistry course.
• To introduce students to essential bioinformatics tools and methodologies.
• To enhance student comprehension of the relationship between protein sequence, structure, and function.

Main Methods:

• Utilized freely available online bioinformatics tools, including Basic Local Alignment Search Tool (BLAST).
• Designed exercises centered around well-characterized proteins: hemoglobin and chymotrypsin.
• Integrated exercises into a computer laboratory setting within the existing biochemistry course structure.

Main Results:

• Students engaged with practical bioinformatics applications relevant to biochemistry.
• The exercises facilitated a deeper understanding of how alterations in protein sequences impact structure and function.
• Provided a scalable model for incorporating bioinformatics into similar undergraduate science courses.

Conclusions:

• The described bioinformatics exercises effectively bridge theoretical biochemistry knowledge with practical computational tools.
• These exercises enhance students' ability to analyze protein data and understand structure-function dynamics.
• Bioinformatics tools can be readily integrated into undergraduate curricula to enrich scientific training.
