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 کاملCrystal structure of yeast phenylalanine transfer RNA. II. Structural features and functional implications.
Thr~ structural features of yeast phenylalanine transfer RNA are analyzed and documented in detail, based on atomic co-ordinates obtained from an extensive crystallographic refinement of t,he crystal structure of the molecule at 2.7 A resolution (see preceding paper). We describe here: the relative orientation and the helicity of the base-paired stems; more definitive assignments of tertiary hy...

Purified yeast phenylalanyl transfer RNA synthetase can aminoacylate three Escherichia co2i transfer RNAs. One of these tRNAs is E. coli valine transfer RNA which has been extensively purified and shown capable of being aminoacylated with phenylalanine and purified yeast phenylalanyl-tRNA synthetase. The extent of this heterologous aminoacylation is approximately 90%. A comparison of the struct...
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...
