- Draw the pyranose form of D-Glucose as a Haworth projection. Identify your projection as either the alpha or beta anomer. Which anomer of D-Glucose is more stable? Why?When performing his experiments on protein refolding, Christian Anfinsen obtained a quite different result when reduced ribonuclease was reoxidized while it was still in 8 M urea and the preparation was then dialyzed to remove the urea. Ribonuclease reoxidized in this way had only 1% of the enzymatic activity of the native protein. Why were the outcomes so different when reduced ribonuclease was reoxidized in the presence and absence of urea?eading list Cells have oligosaccharides displayed on their cell surface that are important for cell-cell recognition. 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.

- Define the term heterodimers6) Proteins can be modified by phosphorylation, which adds a phosphate group to the hydroxyl group of serine, threonine, or tyrosine residues. The R-group for phosphoserine is shown at right. A) The image below is an Isoelectric focusing strip that shows the unphosphorylated protein-of-interest (in blue). To which side of the unphosphorylated protein would you expect to see the phosphorylated protein? (Draw an arrow to indicate direction). Briefly justify your answer. un-phosphorylatable: Low pH Justify: B) To study the effects of phosphorylation, researchers often mutate a Ser/Thr to appear as though it is always phosphorylated or never phosphorylated at a particular site. What amino acid substitution should you use to preserve similar dimensions as Ser (or Thr) but make the side chain appear to be: constitutively (always) phosphorylated: Justify: Ser or Thr → O O=P-O O I CH₂ Ser or Thr➜ Phosphoserine High pHUsing Fischer Projections draw D-Glucose and D-Galactose.
