A specific temperature-dependent conformational transition of hen egg-white lysozyme, occurring between 20 degree C and 30 degree C in solution, has been detected by 13-C-nuclear magnetic resonance spectroscopy. Selective changes in the chemical shifts of aromatic residues, together with differences in the chemical shifts, and nuclear Overhauser enhancement in the carbonyl, carboxyl, and alpha-carbon regions of the spectrum point to the vicinity of subsites D and E as the primary locus of the structural change.
通过13-C核磁共振光谱法已检测到鸡蛋清溶菌酶在溶液中20摄氏度至30摄氏度之间发生的特定温度依赖性构象转变。芳香族残基化学位移的选择性变化,以及光谱中羰基、羧基和α-碳区域化学位移的差异和核Overhauser增强,表明亚位点D和E附近是结构变化的主要位点。
