Science Olympiad Protein Modeling Challenge: Exploring Protein Structure

through Technology

This program is sponsored by a grant from NIH-NCRR-SEPA and the HHMI Pre-College Science Education Program.

What do we do at the Center for BioMolecular Modeling?

•Create accurate 3D molecular models

•Professional development programs

•Science education outreach programs

The CBM offers concrete representations of “invisible” structures.

Protein Models….in 4 Easy StepsProtein Models….in 4 Easy Steps

The Science Olympiad Mission

To promote and improve student interest in science and to improve the quality of K12 science education throughout the nation.

– Identify basic features of protein structure

– Explore protein structure with a computer visualization program

– Create physical models using the flexible modeling media, Mini-Toobers (or alternative materials)

Protein Modeling Event

Pre-Build (40%)•pre-built model based on a PDB file

On-Site Build (30%)•model built on-site during competition

Exam (30%)•questions relating protein structure and function

Visualizing the Molecule


Marking the Toober

• Once a computer visualization image has been determined, secondary structure location should be noted and then marked on the toober.

• Positions of significant amino acids should be marked on the toober as well.

Folding the Toober


Videos online demonstrate how to mark and fold the toober to mimic the image created using the

visualization program

Zinc Finger Folding Activity

• Zinc finger proteins bind DNA

• A zinc finger domain contains a short alpha-helix, 2 beta-strands and conserved Cys, His amino acids that bind a molecule of zinc

Score your model!

Using the rubric provided, score your neighbors’ model of a zinc finger. How well did they do?

What we look for when scoring the models

•Positioning of the blue/red end caps correctly•Correct number of helices/sheets•Correct positioning of helices/sheets (topology)•Right-handed helices•Correct tertiary structure (relative position of helices/sheets to one another)•Model has correct shape (is it globular, saddle shaped, etc)•For prebuild – creative additions to help tell the story•For onsite build – provided amino acids are positioned correctly, on the toober, but also in 3D space (pointing inward or outward)

Common Mistakes

•Blue cap/red cap in wrong position •N-terminus, or the beginning of the protein, is the BLUE cap and C-terminus, or the end of the protein, is the RED cap

•Missing secondary structures•Model has 3 helices, and it should have 4 (or vice versa)

•Left-handed helices•Tertiary structure is incorrect

•Protein should be globular and it is flat•Creative additions on the prebuild are inappropriate

•Incorrect sidechains•Too much information (all of the sidechains)

•Onsite amino acids are positioned incorrectly•In the wrong spot (position 49 rather than 59)•Amino acids are pointing in the wrong direction(should be pointing to the center of the protein and it is facing outward)

The exam

•The exam is a combination of multiple choice and short answers questions.

•Questions cover•Basic chemistry questions regarding atoms, bonds and reactions•Basic protein structure•Structure/function relationship questions•Specific protein questions (for 2010 – Influenza Hemagglutinin and

Neuraminidase)•Application questions (what would happen if…)

•Ties will be broken using specific (labeled)questions on the exam.

Protein Modeling Event Addresses National Science Content Standards
