SNARE helical motifs share a universal length (~60 amino acids). The N’ to C’ terminal zippering to form a highly stable four-helical bundle is thought to provide the energy to fuse membranes. First principles suggest that a longer SNARE four helical bundle would provide greater fusion energy per SNARE bundle, necessitating fewer SNAREs for each membrane fusion. However, families of longer SNAREs (e.g., 120 or 180 amino acids) are unknown. Suggest a possible rationale for why longer SNAREs don’t co-exist...

\Match the following descriptions with the corresponding amino acids: This amino acid is responsible for the strength of rhino horns and wood lignin due to the strong hydrophobic interactions between them. Subtle decreases in the serum pH lead to the protonation of this amino acid, which promotes O2 release from hemoglobin. This amino acid is the nucleophile chymotrypsin uses to attack peptide bonds. This amino acid disrupts α-helices because it makes the nearby protein backbone too flexible (and prevents proper...
