LABORATORY REPORT – PRECIPITATION OF PROTEINS
Step by step
Solved in 2 steps
- Sars-CoV-2 spike protein: VGIYLQKTSDHRPEFALAMN What is its isoelectric point of this peptide?Vasopressin: CYFQNCPRG Oxytocin: CYIQNCPLG Both of these peptides will react with reducing agents such as beta mercaptoethnol (BME). What side group reacts with this reducing agent? What does the fact that these peptides both react with BME tell you about the side groups and therefore this peptide?Vasopressin: CYFQNCPRG Oxytocin: CYIQNCPLG Please calculate the overall charge of the peptides at pH 1,7,9,11 and 14. Are these peptides positvely or negatively charged at pH 7? Between which pH values in this range are the peptides neutral? Calculate the pI of each peptide. How might the differences impact their function?
- Vasopressin: CYFQNCPRG Oxytocin: CYIQNCPLG Calculate the pI of each peptide. How could the differences affect their function.A tetrapeptide, glutamate-glycine-alanine-lysine, is prepared at at concentration of 1 mM (0.001 M) and is measured in the standard setup (pathlength of 1 cm). What is the approximate absorbance of this peptide at 280 nm? Hint: if the peptide contained a single tryptophan, the answer would be about 10. 10 280 1 0whats the amino acid squence for this

- Disease Process of Covid-19Please help! Sketch a titration curve of the peptide Ala-Tyr-Gln-Met-Asp-His from pH=0 to 14 up to 5 equivalnets of KOH (Please type answer)The movements of single motor-protein moleculescan be analyzed directly. Using polarized laser light, it ispossible to create interference patterns that exert a cen-trally directed force, ranging from zero at the center to afew piconewtons at the periphery (about 200 nm from thecenter). Individual molecules that enter the interferencepattern are rapidly pushed to the center, allowing them tobe captured and moved at the experimenter’s discretion.Using such “optical tweezers,” single kinesin mol-ecules can be positioned on a microtubule that is fixed toa coverslip. Although a single kinesin molecule cannotbe seen optically, it can be tagged with a silica bead andtracked indirectly by following the bead (Figure Q16–3A).In the absence of ATP, the kinesin molecule remains at thecenter of the interference pattern, but with ATP it movestoward the plus end of the microtubule. As kinesin movesalong the microtubule, it encounters the force of the inter-ference pattern, which simulates the load…
