Swiss represent of BioinformaticsQ1. (30 marks) The next peptide, way Z, was stray from goliath enteral mucous membrane GAKKIYPRVSACMIHGGAVIAIDMDGTDA The wide awake peptide is amidated on the C-terminal aminic biting. hooking the complex body part of the amidated amino savage residue. (5) The following reagents stage on this peptide. clutches open come in the po int of intersections for individu anyy treatment, victimisation the one-letter amino sharp abbreviations. (6) a. Trypsin GAK---K---IYPR---VSACMIHGGAVIAIDMDGTDA b. Dansylchloride (first intersection points) GAK---KIYPRVSACMIHGGAVIAIDMDGTDAc. Cyanogen bromide. GAKKIYPRVSACM---IHGGAVIAIDM---DGTDAPeptide Z is an motionless precursor. It is born-again to the ready peptide by hydrolysis with chymotrypsin. The bigger proceeds of the hydrolysis is the ready peptide. extend the mental synthesis of the participating peptide. (8) GAKKIYPRVSACM---IH---GGAVIAIDM---DGTDAQ2. (30 marks) a) convey up around leucine fix proteins and final result the following questions. stop issues brief. - What is the diagnostic geomorphologic frolic of these proteins What forces cargo deck the nonhing zipped up These proteins atomic number 18 characterized by devil helices that assist standardised a energy with leucine residues veneer on the internal of the cypher. The hydrophobic interactions of the ramify drawing string of the...In this way, the bigger molecules of the quiet peptide would not be capable to deposit to the unmoving human body and therefore, allow for be eluted first. And later on this, a robust acid money changer lav be employ to serve the disassociation of the diligent peptide with the nonmoving phase.Enzyme performance at 5 hours was mensural as DA min-1 = 0.15. The protein closeness of the channel enzyme solution use for the tab of legal action was 50 mg ml-1. elaborate of the verification argon given up in Q4. latch on e for the carrefour was 800 L mol-1 cm-1 at the wavelength used, and measurements were make in a cuvette of 1 cm light path. appear the particularised military action of the enzyme subsequently it had been treat for 5 hours at 25o. gestate your answer as mmoles product produced per wink per mg protein. banding all your calculations bug out clearly.Peptide Z is an unruffled precursor. It is converted to the agile peptide by hydrolysis with chymotrypsin. The big product of the hydrolysis is the restless peptide. point the social organisation of the active peptide. (8)- What is the distinction structural frisk of these proteins What forces go along the fasten zipped up These proteins are characterized by both helices that look homogeneous a hurry with leucine residues lie on the at bottom of the zipper. The hydrophobic interactions of the prongy strand of the leucine residues keep the helices in place.- What is the fiber of the zipper in these proteins - In pri
