英文摘要 | In the past fifteen years, nuclear magnetic resonance (NMR) has developed into a major structural biology technique, competing favorably with X-ray crystallography. The advantages of NMR are: (1) The ability of NMR in determining the structure of macromolecules near physiological conditions, without the need of growing single crystals. (2) It is capable of extracting kinetic and thermodynamic information related to substrate/ macromolecular interactions at atomic resolution prior to or after the structures have been determined. (3) NMR is the most powerful technique in extracting molecular dynamic information. Taiwan has had good foundation in biomolecular NMR research. Recently, several high field (>500 MHz) NMR Spectrometers had been, or will be installed all over the island. More importantly, several well-trained young biomolecular NMR scientfists have return to Taiwan. We expect biomolecular NMR to flourish in the near future. In this article we briefly discuss the basic principles involved in determining protein structure by modern NMR techniques. |
