摘要
荧光EXAFS数据证实，在HSA和BSA中，锌离子与第一配位层原子的核间距分别为0．201nm和0．203nm，配位数近似为4，很可能为4个氮原子配位，胱氨酸硫原子参与配位的可能性基本排除．
It has been proved that in the Zn(Ⅱ)-HSA and Zn(Ⅱ)-BSA complexes, the in-ternuclear distance between Zn(Ⅱ) and its nearest binding atoms is 0.201 nm and 0.203 nm, the coordinate number is about four, the coordinate atoms are probably nitrogen atoms, and the possibility of sulfur of cysteine binding to Zn(Ⅱ) is basically excluded. The results are consequently discussed.
