- Cut the following protein with the Serine Proteolytic enzyme Trypsin. How many peptide fragments are present after the protein is treated with Trypsin? Val-lle-Arg-Lys-Leu-Arg-Gly-Ala-Lys-lle 6. 10Show where trypsin and chymotrypsin would cleave the following peptide Tyr-Ile-Gin-Arg-Leu-Gly-Phe-Lys-Asn-Trp-Phe-Gly-Ala-Lys-Gly-Gin GinThe 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 DPG
