Like lysine, it has an unusually flexible sidechain that allows it to adopt a very large number of conformations, important in biological processes such its major presence in receptor proteins that allow only hydrophobic molecules through.
Like lysine, it has an unusually flexible sidechain that allows it to adopt a very large number of conformations, important in biological processes such its major presence in receptor proteins that allow only hydrophobic molecules through. Its terminal methyl group on its sidechain often participates in biochemical methyl transfer reactions making it a member of the "methyl donor" class of biochemicals. For ten points, name this essential amino acid, one of only two-sulfur-containing-DNA-encoded amino acids, and the first amino acid incorporated into the N-terminal position of all eukaryotic proteins.
