Yeast phenylalanine transfer RNA: atomic coordinates and torsion angles.
The atomic coordinates of yeast phenylalanine transfer RNA (tRNA) as well as the torsion angles of the polynucleotide chain are presented as derived from an x-ray diffraction analysis of orthorhombic crystals. A comparison is made between the coordinates obtained from analysis of monoclinic crystals of the same material. It is concluded that the molecule has substantially the same form in the o...
متن کاملIdealized atomic coordinates of yeast phenylalanine transfer RNA.
The atomic coordinates are given for yeast phenylalanine transfer RNA in the orthorhombic crystal form. The structure has been refined by fitting to successively improved electron density maps at 2.7 8 resolution. The model fitting has been accomplished by using an interactive computer graphics system to minimize the errors inherent in manual model building and coordinate measurements, using an...
متن کاملHydrogen bonding in yeast phenylalanine transfer RNA.
Further analysis of the three-dimensional electron density map of yeast phenylalanine tRNA is presented. Attention is focused on the several types of unique hydrogen bonding that are found in the molecule and a number of sections of the electron density map are presented. These sections are compared with an electron density map of a dinucleoside phosphate. The bases in the helical stem regions ...
متن کاملThree-dimensional tertiary structure of yeast phenylalanine transfer RNA.
The 3-angstrom electron density map of crystalline yeast phenylalanine transfer RNA has provided us with a complete three-dimensional model which defines the positions of all of the nucleotide residues in the moleclule. The overall features of the molecule are virtually the same as those seen at a resolution of 4 angstroms except that many additional details of tertiary structure are now visual...
متن کاملAtomic co-ordinates for yeast phenylalanine tRNA.
Atomic coordinates are presented for yeast tRNA(Phe) derived from a wire skeletal model fitted to an electron density map at 2.5 A resolution obtained by isomorphous replacement.
