Textbook Question
Chapter 6.7, Problem 3CC
MAKE CONNECTIONS Ø The polypeptide chain that makes up a tight junction weaves back and forth through the membrane four times, with two extracellular loops, and one loop plus short C-terminal and N-terminal tails in the cytoplasm. Looking at Figure 5.14, what would you predict about the amino acid sequence of the tight junction protein?

Approximately how many amino acids must a helical transmembrane segment of an integral membrane protein have if the segment is to span the lipid bilayer defined by two stearate molecules laid end to end, plus the polar head groups to which the stearate molecules are attached (assume a polar head group has a diameter of 0.5 nm)?arrow_forward
- I'm honestly confused on where to start with this question. I think it has something to do with the residues per turn but can you please explain and show detailed work on the the problem. Researchers have discovered a new membrane protein that has three transmembrane domain αhelixes that span the lipid bilayer. a. If the lipid bilayer is 30 Å thick, what is the smallest number of amino acid residues that can be in each α-helixes for them to be long enough to span the bilayer? b. If one of the three α-helixes is titled at a 32° angle relative to an axis perpendicular to the surface of the lipid bilayer, what is the smaller number of amino acid helixes required for that helix to still span the lipid bilayer? c. How many hydrogen bonding interactions would there be in the smallest possible tilted transmembrane α-helix? d.

The threonine residues act as membrane interface anchors, interacting with the lipid bilayer and the aqueous environment. The amphipathic helix interacts with the lipid bilayer along its hydrophobic surface, exposing its hydrophilic surface to the aqueous environment. A group of helices cluster with their polar surfaces in contact with one another and their hydrophobic surfaces facing the lipid bilayer. The peptide entirely embeds in the lipid bilayer.
