The six 13Czeta resonances of the 6 tyrosine residues of ribonuclease A have been resolved by high field 13C Fourier transform nuclear magnetic resonance spect=oscopy. Titration studies of these resonances reveal 1 nontitrating or buried tyrosine residue, 1 partially buried residue, and 4 normally titrating residues, which are tentatively identified.
核糖核酸酶A的6个酪氨酸残基的6个13Cζ共振峰已通过高场13C傅里叶变换核磁共振光谱法得以分辨。对这些共振峰的滴定研究揭示出1个非滴定或埋藏型酪氨酸残基、1个部分埋藏型残基以及4个正常滴定型残基,这些残基已得到初步鉴定。
