Chapter 4: protein structure
Cards in this deck (11)
- 1active siteregion on enzyme surface that binds to substrate molecule and catalyze chemical transformation
- 2allostericprotein that exists in multiple conformations depending on molecule bonding at a site other than the catalytic site
- 3alpha helixcommon folding pattern, a single polypeptide chain twists around itself forming a rigid cylinder; hydrogen bonds every 4th amino acid
- 4amino acid sequenceorder of amino acid subunits (primary structure of protein)
- 5antigenmolecule recognized by an antibody
- 6beta sheetsfolding pattern; polypeptide chain associate side by side together through a hydrogen bond; rigid flatten structure
- 7binding sitecavity or groove that interacts with another molecule (ligand); through non-covalent bonds
- 8c-terminusend of polypeptides chain that carries a free carboxyl group (-cooh)
- 9chromatographyused to separate the individual molecules in a complex mixture on the basis of their size, charge, or their ability to bind to a particular chemical group
- 10coiled-coilstable, rodlike protein structure formed when two or more alpha helices twist around each other
