Chapter 21, Problem 4TYU
DRAW IT Below are the amino acid sequences(using the single-letter code; see Figure 5.14) of four short segments of the FOXP2 protein from six Speeles: chimpanzce (Q, orangutan (()), gorllla (G), rhesus macaque (R), mouse (M), and human (H). These segments contain all of the amino acid differences helween the FOXP2 proteinsof these species.
Use a highlighter to color anv amino acid that varies among the species. (Color that amino acid in all sequences.
- (a) The C, G, R sequences are identical. Identily which lines correspond to those sequences.
- (b) The O sequence differs from the C, G, R speieces at two amino acids. Underilnethetwodlffcrences inthe H sequence.
- (c) The O sequence diffen from the C, G, R sequences at one amino acid (having V instead of A) and from the H sequence at three amino acids. Identify tho O sequence.
- (d) In the M sequence,circle the amino acid(s) that differ from the C, G, R sequence, and draw a square around those that differ from the H sequence.
- (e) Primates and rodents diverged between 60 and IO0 million years ago. and chimpanzees and humans about 6 million years ago. Compare the amino acid differences between the mouse and the C, G, R species with those between the human and the C, G, R species. What can you conclude?

You have discovered a novel protein that has a pI = 5.5. To study the functional properties of this new protein, your research group has made a mutant that contains two amino acid changes—namely, a surface Phe residue in the normal protein has been replaced by His (side chain pKa = 6.1) and asurface Gln has been replaced by Glu (side chain pKa = 6.0). Is the pI of themutant protein predicted to be greater than, less than, or the same as the pIof the normal protein? Support your answer with the appropriate calculation.
