Many cell surface or extracellular proteins are glycoproteins, as are most secreted proteins. List three purposes which the covalently attached oligosacharide portion of glycoproteins serves.
Homework Answers
Glycoproteins are proteins which contain oligosaccharide chains which is covalently attached to amino acid side-chains.
3 function of oligosaccharide portion of glycoprotein are :-
1)They play important role in cell to cell interaction
2) They are chemical markers used to tag proteins destined to be used outside the cell.
3)Protect from proteolysis from inside and outside of cell

Which of the following statements is NOT correct? A. Glycoproteins can have the carbohydrates in either O-glycosidic bonds to Ser or Thr residues or in N-glycosidic bonds to Lys residues. B. Glycosylated proteins are generally either extracellular proteins or membrane proteins with the carbohydrate residues on the extracellular side of the membrane. C. Penicillin is a mechanism-based inhibitor of a transpeptidase required for bacterial cell wall synthesis. D. Proteoglycans are composed of core proteins with one or more attached glycosaminoglycans....

SDS-PAGE is often used to determine the location and orientation of membrane associated proteins. Commonly, experimental preparations of membranes are treated in a variety of ways in order to extract the proteins, which are then subjected to SDS-PAGE. These treatments will affect membrane proteins in different ways, based on how they are arranged in the membrane. One of the most common pre-treatments is by the digestive enzyme trypsin, which degrades polypeptide chains. Trypsin is too large to cross a membrane,...

Question 10-12
10. During the mating process, yeast cells respond to pheromones secreted by other yeast cells. These pheromones bind GPCRs on the surface of the responding cell and lead to the activation of proteins inside the cell. When a wild-type yeast cell senses the pheromone, its physiology changes in preparation for mating: the cell stops growing until it finds a mating partner. If yeast cells do not undergo the appropriate response after sensing a pheromone, they are considered sterile....
