Presentation Transcript

  1. DNA encodesmessenger RNA DNA = Information transcription mRNA = Message translation Protein sequence = Assembly folding Folded protein = Function

  2. Ribosome mRNA encodes proteins DNA = Information transcription mRNA = Message translation Protein sequence = Assembly folding Folded protein = Function

  3. Protein folding Folding intermediates of apomyoglobin DNA = Information transcription mRNA = Message translation Protein sequence = Assembly folding Folded protein = Function U = unfolded E = early intermediate I = intermediate N = native

  4. Levels of Protein Structure: Secondary Structure • ordering along short stretches of the protein b-sheets a-helices

  5. Levels of Protein Structure: Tertiary Structure • overall conformation of the protein chain • information contained in the protein’s sequence of residues is sufficient to dictate the specific 3-dimensional structure that the chain will adopt (“native state”)
