Fluorescent proteins like the green fluorescent protein (GFP) found in jellyfish are a class of colorful proteins that shine a particular color when exposed to ultraviolet light. These proteins, despite exhibiting a wide range of diverse colors, have nearly identical secondary structure across organisms and phenotypes. Each GFP-like protein has a few alpha-helices as well as a characteristic beta-barre composed of 11 beta-sheets that shields the inside of the protein from solvent (i.e., water). The GFP like protein shown below is a green fluorescent protein from the great star coral Montastraea cavernosa and contains two alpha-helices in its structure (labeled A and B and colored cyan). A B 1. Helix A contains 6 amino acids, including a phenylalanine and an aspartic acid. Which position (1 or 2, colored in red) would you more likely expect aspartic acid to be located? [ Select] 2. If you were to compare helix A to helix B, would you expect the ratio of polar:non-polar residues to be higher or lower in helix B? [ Select]
