This document represents a second laboratory assignment for Bioinformatics II (BIO 3352) at New York City College of Technology. It focuses on protein visualization using molecular graphics software, likely PyMOL, based on the interface screenshots provided. The assignment is designed for students to practice representing protein structures in different styles and interpreting those representations.
This lab is essential for students learning to analyze protein structure, a core skill in bioinformatics. It’s likely used during a unit covering protein structure visualization and analysis techniques. Students will need this assignment to demonstrate their ability to manipulate and interpret protein models.
This document does *not* provide instruction on the underlying principles of protein structure or bioinformatics concepts. It also doesn’t offer solutions to the questions posed. It’s a practical exercise, and students will need prior knowledge of protein structure and the software interface to complete it.
This assignment includes screenshots of a protein (1ubq) visualized in NewCartoon and CPK representations, along with questions prompting students to: identify the atoms used in NewCartoon representation, create specific protein renderings, analyze the advantages of CPK vs. VDW representations, and interpret the distribution of hydrophobic and hydrophilic residues. It also includes prompts to analyze the protonation states of titratable amino acids and infer a plausible pH for the protein’s environment.
