Lecture, chapter 7 - Protein structure and function

Today we continued with the chapter in protein structure and function.

We discussed the most common shapes found in the secondary structure of proteins, α-helices and β-sheets. Me mentioned the typical ways in which they refold to obtain their tertiary structure.

We talked how can proteins "read" DNA information without separating the strands in the double helix and the most common DNA-binding motifs found (helix-turn helix, helix-loop-helix, leucine zipper, zinc finger).
