Question

4. Draw the predominating structure of TEACH at pH 5. (5 pts) 5. Draw the predominating structure of CADET at pH 11. (5 pts) 6. Below is part of the amino acid sequence of a protein that contains both a loop and another secondary structure. ...LEALKFELSRAMSTYEAFNVSLRVVDTVPSEGEPDDAKRRSGVG... a) Draw a circle around the sequence that code for the loop. Cite three structural features that support this being a loop, or, alternatively, do not support it being an alpha-helix. (6 pts) b) Draw a box around the sequence that codes for the other secondary structure. Cite three structural features that support this region being what you think it is. State two stabilizing factors that hold this together. (10 pts-6 pts for features and 4 pts for attractions) 7. For the ribbon diagram below, indicate what type of secondary structure (a-helix, parallel \beta-sheet antiparallel \beta-sheet, loop) is shown at regions a) through d). (8 pts-2 ea.)
