This figure shows the results of a 2-dimensional gel that was run to separate the proteins found in a snake toxin. Locate the prominent dark spot in the upper right-hand quadrant on the 2-dimension gel and answer these questions.  Name one thing that you can infer about that amino acid composition of this major spot from the isoelectric focusing direction of the gel?  What is one thing that you can infer from the PAGE direction of this gel about this protein? Image Source: Hatakeyama, et al. (2018) Image Description  A 2-Dimensional Electrophoresis (2-DE) gel showing the separation of proteins. The x-axis represents the pH range from 3 to 10, and the y-axis represents molecular weight from 15 kDa to 250 kDa. Multiple protein spots are visible, indicating their isoelectric points and molecular weights. The label “A” marks a significant area of interest on the gel. The gradient shading reflects the concentration of proteins, with darker spots representing higher protein abundance.

 The G-75 fraction that contains the desired biological activity is further separated on a Mono-S column, which is a cation exchange column. Briefly describe the characteristics of a protein that binds to a Mono-S column and the role of the NaCl gradient in this type of chromatography.

  Upload an image of your answer to this question. Draw the complete structure of a tripeptide (three amino acid residues) of your choice that contains an amino acid with a neutral R group capable of forming H-bonds (residue 1), a second amino acid with an R group that has an isopropyl structure (residue 2), a third amino acid with an R group containing two fused aromatic rings (residue 3). Label each amino acid with its three-letter code and assume a pH of 7.4.
