The major codon specifying initiation of translation is AUG. Rose & al Ratio hetero end/side Average area buried Average flexibility alpha-helix / Chou & Fasman beta-sheet / Chou & Fasman beta-turn / Chou & Fasman alpha-helix / Deleage & Roux beta-sheet / Deleage & Roux beta-turn / Deleage & Roux Coil / Deleage & Roux alpha-helix / Levitt beta-sheet / Levitt beta-turn / Levitt Total beta-strand Antiparallel beta-strand Parallel beta-strand A.A. Hydrophobic amino acids are often encoded by codons with U in the 2nd position, and all codons with U at the 2nd position encode hydrophobic amino acids. Rf mobility HPLC / HFBA retention HPLC / TFA retention Transmembrane tendency HPLC / retention pH 2.1 HPLC / retention pH 7.4 % buried residues % accessible residues Hphob. The primary level is the sequence of amino acids in the polypeptide chain. Much less attention has been paid to hydrophobic sequences within globular proteins. Molecular weight Number of codon(s) Bulkiness Polarity / Zimmerman Polarity / Grantham Refractivity Recognition factors Hphob. There are four levels of protein structure that contribute to the overall three-dimensional shape of a folded protein. Long, predominantly hydrophobic strings of 2022 amino acids each are associated with transmembrane helices and have been used to identify such sequences. To display information about a scale (author, reference, aminoĪcid scale values) you can click on its name. Please choose an amino acid scale from the following list.
