The major difference between a protein molecule in its native state and in its denatured state lies in the number of conformations avail- able. To a first approximation, the native, folded state can be thought to have one conformation. The unfolded state can be estimated to have three possible orientations about each bond between residues. (a) For a protein of 100 residues, estimate the entropy change per mole upon denaturation. (b) What must be the enthalpy change accompanying denaturation to allow the protein to be half-denatured at 50 °C? (c) Will the fraction denatured increase or decrease with increasing temperature?
Consider the following tetrapeptide, written in a sequence according to normal convention, from left to right: Residue 1 is acidic; Residue 2 is proline (a large hydrophobic amino acid); Residue 3 is cysteine (an amino acid containing a -CH2SH R-group); Residue 4 is basic. Which of the following four general statements is TRUE regarding this tetrapeptide? This tetrapeptide probably is not part of an alpha-helix, since the large size of the proline would disrupt the consistency of the spiral shape. Residue 3 belongs to the amino acid category known as "basic." This tetrapeptide has the ability to form a disulfide linkage with an identical tetrapeptide. The acidic residue (Residue #1) is at the amino terminus of this tetrapeptide. 3 of these 4 responses are correct
This SDS-PAGE loading buffer has SDS (a denaturing detergent), β-mercaptoethanol (a reducing agent), Coomassie Blue (a dye), and glycerol. You will need to dilute your protein samples such that the final concentration of the loading buffer is 1x, meaning that you will add 5 parts of the protein sample for every 1 part of 6x buffer. Calculate how much of the 6x loading buffer you will need to add to each sample. Then, add the appropriate amount of 6x SDS-PAGE loading buffer to the samples. Store the samples in the -20°C freezer. What is the final concentration of glycerol in each of the samples?
