- Which amino acid pair constitutes the hydrophobic patch on sickle cell hemoglobin that results in formation of protein oligomers with the Glu 6 --> Val 6 sickle cell mutation? Does normal hemoglobin contain this same amino acid pair constituting a hydrophobic patch? Phe 85 / Leu 88; no Phe 85 / Leu 88; yes Trp 85 / Leu 88; yes Olle 85 / Leu 88; yes Pro 85 / Lys 88; noAn "AA" genotype at the ALOX5AP -4900 A>G locus acting in the 5-lipoxygenase pathway may increase risk of breast cancer when intake of which fatty acid is high? a) Stearic acid b) Eicosapentanoic acid c) Linoleic acid d) Alpha-linolenic acidCertain individuals with mild forms ofβ-thalassemia produce, in addition to normal adulthemoglobin with two α chains and two β chains,lower levels of an unusual, so-called Leporehemoglobin with two α chains and two chains ineach of which the N-terminal half comes from anormal δ chain and the C-terminal half comesfrom a normal β chain. Certain other individualswho are asymptomatic produce a different, unusualanti-Lepore hemoglobin that contains two α chainsand two chains in which the N-terminal half comesfrom a normal β chain and the C-terminal halfcomes from a normal δ chain.a. Describe an event that could give rise to bothLepore and anti-Lepore hemoglobins
- Certain individuals with mild forms ofβ-thalassemia produce, in addition to normal adulthemoglobin with two α chains and two β chains,lower levels of an unusual, so-called Leporehemoglobin with two α chains and two chains ineach of which the N-terminal half comes from anormal δ chain and the C-terminal half comesfrom a normal β chain. Certain other individualswho are asymptomatic produce a different, unusualanti-Lepore hemoglobin that contains two α chainsand two chains in which the N-terminal half comesfrom a normal β chain and the C-terminal halfcomes from a normal δ chain.a. Describe an event that could give rise to bothLepore and anti-Lepore hemoglobins.b. Are the mildly thalassemic individuals with Leporehemoglobin homozygotes or heterozygotes for theunusual allele?c. Why might these mildly thalassemic people produce less Lepore hemoglobin than normal adulthemoglobin?Which of the following mutations would most likely keep the transitions of T state to R state in hemoglobin unchanged, or similar to the transitions that occur in the native molecule? The three-letter codes for amino acids are used, and the numbers following the amino acids designate the amino acid position in the protein. By convention, the original, native amino acid is listed fırst, followed by the mutational change. Choose one: O A. Asp94→Ile94 O B. Tyr42→Phe42 O C. Asp94 Glu94 O D. Tyr42-Gly42Hemoglobin is considered to be a tetrameric complex with a 64 kDa (α β)2. When attempting to purify hemoglobin, we must first purify the α and β monomers (about 16 kDa each) to prepare the tetramer. This is formed from the dimer intermediate: 2 α + 2 β -> 2 αβ -> (α β)2. The graph given represents a size-exclusion chromatogram after the refolding of the hemoglobin tetramer Using the size-exclusion chromatogram given, 1. Draw an SDS-Page Gel with a reducing agent such as BME using the three peaks listed on the graph.
- In some metalloproteins such as haemoglobin and some metalloenzymes, the Fe2+ metal is not bound to the amino acid side-chains of the protien,but to a prophrin ring called a heme prosthetic group. How does the heme coordinate to the iron?The figure shows interaction of various amino acids (Phe, Arg, and Asn) present in Hb with 2,3-DPG. The side chains of these amino acids and 2,3-DPG interactions are circled in red. HO Но Phe HN Asn H2N NH Arg You identify a mutant version of the globin chain where the Arg in circle 2 is replaced with aspartic acid in a patient. Would the Hb protein in this patient be able to transport oxygen even in the presence of 2,3-DPG? ASPARTIC ACID (asp) No, because the mutant Hb version will bind 2,3 DPG, and not oxygen Yes, because the mutant Hb version will bind 2,3 DPG, and not oxygen Yes, because the mutant Hb version will bind oxygen and not 2,3 DPGWe note in Figure 10-14 that the structure of glycosphingolipids determines the blood groups A, B, and O in humans. It is also true that glycoproteins determine blood groups. How can both statements be true?
- What is the effect of the altered amino acid sequence in Hb S that causes the cells to form sickle shapes?A) Upon entering the body, CH3H9+ reacts with cysteine to form a molecule that is able to pass through the blood brain barrier (BBB). Draw the structure of this molecule and purpose why it is able to pass through the BBB (Hint: think about another amino acid). B) The adduct formed in part A is very labile. On encountering selenocysteine, it can permanently inhibit it. Propose how the adduct from Part A inhibits selenocysteine and explain your answer.What are two features D-Glucosaminate-6-phosphate Ammonia-lyase structure that make either it different OR similar to haemoglobin?
