slowly than the column, mutant protein Y runs through the column more Which of the following changes in the mutant protein is most likel 2018 Osman, Cell Bio 3201, SPRING the Colutrhtein is most likely to explain filtration column, this result? athe loss of a binding site on the mutant-p rotein surface through which protein Y normally forms dimers achange tre in acquiring an overll positive instead ot e achange that results in the mutant protein being larger than the wild-type protein ( a change that results in the mutant protein having a slightly different shape from a negative charge the wild-type protein 444 Which of the following statements is true? a) Disulfide bonds are formed by the cross-linking of methionine residues. (b) Disulfide bonds are formed mainly in proteins that are retained within the cytosol. (e) Disulfide bonds stabilize but do not change a protein's final conformation. (d) Agents such as mercaptoethanol can break disulfide bonds through oxidation.

The selection of one ligand out of a mixture of possible ligands depends on the number of weak, noncovalent interactions in the protein's ligand-binding site. Where is the binding site typically located in the protein structure? (a) on the surface of the protein (b) inside a cavity on the protein surface (c) buried in the interior of the protein Page 12 of 20Explanation / Answer
