. Phosphatidylserine (PS) is considered to be an intermediate in the biosynthesis of phosphatidylethanolamine (PE) in E. coli, yet PS is not found in appreciable amounts among E. coli membrane phos- pholipids. Because PS must be present in the membrane to serve as an intermediate, how might you explain its failure to accumulate to a significant extent? What kinds of experiments could test your pro- posed explanation?

Consider a protein with two surface-exposed histidine residues: HisA is a “typical” histidine residue with a pKa = 6.2 HisB is involved in a stabilizing interaction (His-NH+ ..... -O2C-Glu) with a neighboring glutamic acid residue. For HisB, the Gibbs free energy of deprotonation at pH = 7.0 and T = 293K is ΔG'o = +15 kj mol-1. If you had a solution, at pH = 7.0 and T = 293K, containing this protein: a) What fraction of HisA residues are protonated? b) What fraction of HisB residues are protonated? c) What is the pKa of HisB?
D-glucose is added to cells and the rate of glucose transport is plotted against D- glucose concentration. In the presence of the D-galactose derivative 6-0-benzyl-D- galactose, the curve is shifted to the right, indicating that D-glucose and the D- galactose derivative both compete for a place in the binding site. External factors such as the addition of ATP or ion gradients doesn't change the rate of absorption into cells. Which of the following is true, select all that apply: O the enzyme is a uniport O mediated transport is occurring O non-mediated transport occurring O passive transport is occurring O active transport is occurring
1. The CFTR protein is a chloride channel in the cell membrane. Use your understanding of the biochemical properties/categories of amino acids and how they interact with membrane phospholipids to predict the distribution of charged/polar, and non-polar amino acids within the domains of CFTR listed below. Consider one category to include the charged amino acids and the polar amino acids and the other category to include the non-polar amino acids. For each domain, predict which category of amino acids is likely to be most abundant. Also, explain the rationale behind your prediction.

At body temperature, L-aspartate in proteins race-mizes to D-aspartate at an appreciable rate. Most pro-teins in the body have a very low level of D-aspartate, if itcan be detected at all. Elastin, however, has a fairly highlevel of D-aspartate. Moreover, the amount of D-aspartateincreases in direct proportion to the age of the person fromwhom the sample was taken. Why do you suppose thatmost proteins have little if any D-aspartate, while elastinhas levels of D-aspartate that increase steadily with age?
