Citation | Journal: J Mol Biol / Year: 1987 Title: Structure of ubiquitin refined at 1.8 A resolution. Abstract: The crystal structure of human erythrocytic ubiquitin has been refined at 1.8 A resolution using a restrained least-squares procedure. The crystallographic R-factor for the final model is 0.176. Bond ...The crystal structure of human erythrocytic ubiquitin has been refined at 1.8 A resolution using a restrained least-squares procedure. The crystallographic R-factor for the final model is 0.176. Bond lengths and bond angles in the molecule have root-mean-square deviations from ideal values of 0.016 A and 1.5 degrees, respectively. A total of 58 water molecules per molecule of ubiquitin are included in the final model. The last four residues in the molecule appear to have partial occupancy or large thermal motion. The overall structure of ubiquitin is extremely compact and tightly hydrogen-bonded; approximately 87% of the polypeptide chain is involved in hydrogen-bonded secondary structure. Prominent secondary structural features include three and one-half turns of alpha-helix, a short piece of 3(10)-helix, a mixed beta-sheet that contains five strands, and seven reverse turns. There is a marked hydrophobic core formed between the beta-sheet and alpha-helix. The molecule features a number of unusual secondary structural features, including a parallel G1 beta-bulge, two reverse Asx turns, and a symmetrical hydrogen-bonding region that involves the two helices and two of the reverse turns. #1: Journal: J.Biol.Chem. / Year: 1987 Title: Comparison of the Three-Dimensional Structures of Human, Yeast, and Oat Ubiquitin Authors: Vijay-Kumar, S. / Bugg, C.E. / Wilkinson, K.D. / Vierstra, R.D. / Hatfield, P.M. / Cook, W.J. #2: Journal: Proc.Natl.Acad.Sci.USA / Year: 1985 Title: Three-Dimensional Structure of Ubiquitin at 2.8 Angstroms Resolution Authors: Vijay-Kumar, S. / Bugg, C.E. / Wilkinson, K.D. / Cook, W.J. #3: Journal: J.Mol.Biol. / Year: 1979 Title: Crystallization and Preliminary X-Ray Investigation of Ubiquitin, a Non-Histone Chromosomal Protein Authors: Cook, W.J. / Suddath, F.L. / Bugg, C.E. / Goldstein, G. #4: Journal: Nature / Year: 1975 Title: Molecular Conservation of 74 Amino Acid Sequence of Ubiquitin between Cattle and Man Authors: Schlesinger, D.H. / Goldstein, G. | ||||||
