- The transmembrane segments of most integral membrane proteins are made of alpha -helical secondary structures. What is the advantage of this conformation ? How do multiple alpha-helices arrange themselves to form the aqueous pore of an ion channel ?The predominant forms of actin inside a cell are ATP–G-actin and ADP–F-actin. Explain how the interconversion of the nucleotide state is coupled to the assembly and disassembly of actin subunits.Heparin, a highly negatively charged glycosaminoglycan, is used clinically as an anticoagulant. It acts by binding several plasma proteins, including antithrombin III, an inhibitor of blood clotting. The 1:1 binding of heparin to antithrombin III seems to cause a conformational change in the protein thatgreatly increases its ability to inhibit clotting. What amino acid residues of antithrombin III are likely to interact with heparin?
- What are the FOUR ways that protein function is regulated (function turned ON/OFF). Explain each.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 thatcan be in each α-helixes for them to be long enough to span the bilayer?The lipid composition of the cytosolic and extracellular leaflets of the the cell membrane is described as asymmetric. Explain what is meant by "cell membrane asymmetry" and how it can be used to regulate a cellular process such as apoptosis.
- Which one of the following is NOT true about ECM? O ECM is composed of an interlocking mesh of fibrous proteins and glycosaminoglycans. O ECM supports cell-to-cell communication and stem cell differentiation. O Proteoglycan complex has a unique bottle brush-like structure. It is positively (+) charged. It is composed glycosaminoglycans and carbohydrates that are attached to the proteins. O ECM is a collection of extracellular molecules secreted by cells that provides structural and biochemical support to the surrounding cells.Arctic fish produce large amounts of antifreeze proteins during cold winter months. These proteins prevent water from forming large ice crystals and damaging soft tissue. a. Would you expect these proteins to be hydrophobic or hydrophilic? b. Do you think they are transmembrane transport proteins? If so, do you think them to be of channel/carrier/pumps? (A)Non covalent bonds are very important in cell biology, could you explain why and provide an example that illustrates their importance ( do not chose protein folding as an example) What are the different levels of protein structure and what are the different parameters (sequence, type of bonds, etc...) that influence protein folding at these different levels?
- Disulfide linkages are uncommon in cytoplasmic proteins, whereas they are common in extracellular proteins. Why?The concentration of actin in cells is 50–100 timesgreater than the critical concentration observed for pureactin in a test tube. How is this possible?
