Chapter 9, Problem 2DAA
Summary Introduction
To determine: The concentration of RIP at which all of different kinds of cancer cells survive.
Introduction: Ribosome-inactivating proteins (RIPs) inactivate the ribosomes and prevent protein synthesis in a cell. It removes adenine base from ribosomal rRNA that forms the part of binding site for proteins involved in GTP. This results in inability of ribosome to bind to these proteins and protein synthesis stops. The toxic RIPs have a domain that makes them enter into another that interferes with ribosome. They have antiviral and anticancer properties, and are used to design drugs for HIV and cancer.

E. coli ribonuclease H1 is an enzyme that catalyzes the hydrolysis of phosphodiester bonds in RNA. Its proposed mechanism involves a 'carboxylate relay,' as shown below. His124 Asp70 || -HN-CH-C -HN-CH-C- CH2 CH2 c=0 RNA substrate HN H. H. (1) Fill the blanks. In the reaction scheme above, His124 acts as a ( ). The purpose of this relay system is to deprotonate the water molecule (II) so that it becomes a better ( :0

- Figure 15.16 Many antibiotics inhibit bacterial protein synthesis. For example, tetracycline blocks the A site on the bacterial ribosome, and chloramphenicol blocks peptidyl transfer. What specific effect would you expect each of these antibiotics to have on protein synthesis? Tetracycline would directly affect: tRNA binding to the ribosome ribosome assembly growth of the protein chain Chloramphenicol would directly affect tRNA binding to the ribosome ribosome assembly growth of the protein chainarrow_forwardAnalyse and interpret the SCAM data in Fig. 1, and make a table (remember to include a legend) to indicate where each amino acid is located (cytoplasm, membrane, periplasm).arrow_forwardMCQarrow_forward

Your friend has discovered a transmembrane glycoprotein, GP1, on a pathogenic fungal cell that is recognized by human immune cells. He decides to purify large amounts of GP1 by expressing it in bacteria. To his purified protein he then adds a branched 14-sugar oligosaccharide to the asparagine of the only Asn-X- Ser sequence found on GP1. Unfortunately, immune cells do not seem to recognize this synthesized glycoprotein. What's a likely explanation for this problem? O The oligosaccharide needs to be further modified before it's mature. O The oligosaccharide should've been added one sugar at a time. O The oligosaccharide needs a disulfide bond. O The oligosaccharideehould've been added to the serine instead of the asparagine.arrow_forwardOnce the chains of peptides that make up lysyl-tRNA synthetase protein are synthesized in ribosomes, lysyl-tRNA synthetase needs to have the proper active site in order to perform its function, explain the process of protein folding necessary to have a proper 3-D structure, include effect of thermodynamics and different states in folding, including what happen when there are prolines that form peptide bonds with other amino acids, and any disulfide bridgesarrow_forward

- This answer is incorrect pls provide the right answer and explanationarrow_forwardI need an example to study for an testarrow_forwardMany blood clotting proteins undergo a post-translational modification in which specific glutamic acid residues (Glu) in the protein are converted to gamma-carboxyglutamic acid residues (Gla). See reaction scheme below. An example is the blood clotting protein Factor IX, which has 12 Glu in its N-terminus converted to Gla. This modification gives Factor IX the ability to bind calcium and phospholipid membranes. Bacteria do not have the enzyme required to convert Glu to Gla and therefore Factor IX proteins expressed in bacteria would not have the proper modifications. How might you engineer the translational apparatus of a bacterial cell line so that it produces Factor IX with Gla in the appropriate positions. How would you ensure that only the 12 Glu in Factor IX that are normally converted to Gla and not just all Glu (Limit 5-6 senetnces)?arrow_forward
