SOLUTION STRUCTURE OF THE RNASE P RNA (M1 RNA) P4 STEM OLIGORIBONUCLEOTIDE
Solution structure and metal-ion binding of the P4 element from bacterial RNase P RNA.
THE WILDTYPE P4 STEM OLIGORIBONUCLEOTIDE COMPLEXED WITH COBALT (III) HEXAMMINE
THE C70U MUTANT P4 STEM OLIGORIBONUCLEOTIDE
synthesized from DNA oligonucleotide template by T7 RNA polymerase
This structure was determined using standard 2D homonuclear techniques and 13C and 31P heteronuclear techniques at natural abundance
The average structure is based on superposition of nine converged structures after refinement. The average RMS deviation between the ensemble and the average structure is 1.8 Angstrom. A total of 266 NOE-derived distance constraints, 164 dihedral restraints and 48 distance restraints from hydrogen bonds were used in the refinement
