'group G'. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance. Method: X-ray diffraction, Resolution 2.15Å Ligands: ACT, AIB, B3K, NH2 Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function SPG2_STRSG Publication Abstract from PubMed We report here the comparison of five classes of unnatural amino acid building blocks for their ability to be accommodated into an alpha-helix in a protein tertiary fold context. High-resolution structural characterization and analysis of folding thermodynamics yield new insights into the relationship between backbone composition and folding energetics in alpha-helix mimetics and suggest refined design rules for engineering the backbones of natural sequences. Comparison of design strategies for alpha-helix backbone modification in a protein tertiary fold.,Tavenor NA, Reinert ZE, Lengyel GA, Griffith BD, Horne WS Chem Commun (Camb). 2016 Feb 25;52(19):3789-92. doi: 10.1039/c6cc00273k.
