3. Shown below is a typical hydropathy plot for bacteriorhodopsin as described in question 2. a) Draw a horizontal bar over each transmembrane segment. (2pts) 4.0 2.0 0 -2.0 -4.0 0 20 40 60 80 100 120 140 160 180 200 220 240 Amino acid number b) How long is the average transmembrane segment as determined from the plot? (2 pts)

Solution

Solution:

The transmembrane segments of the polypeptide chain will have hydrophobic amino acids which have a positive hydrophobicity value. higher the positive value higher the hydrophobicity.

average length of transmembrane segment is 20 amino acids.
