We have investigated the conformational features of four short peptide fragments of Staphylococcal nuclease by homonuclear two-dimensional NMR and circular dichroism with a view to examining the early events in the folding process of SNase.

中文题名金黄色葡萄球菌核酸酶折叠起始位点：N-末端短肽段的NMR研究副题名外文题名 Folding initiation sites of staphylococcal nuclease：exploring the solution conformation of N-terminal fragments by nuclear magnetic resonance 论文作者戴继勋导师王金凤研究员学科专业分子生物学研究领域\研究方向学位级别博士学位授予单位中国科学院生物物理研究所学位授予日期2001 论文页码总数68页关键词金黄色葡萄球菌核酸酶蛋白质折叠核磁共振馆藏号BSLW /2001 /Q71 /89 本论文工作用四个金黄色葡萄球菌核酸酶N-末端短片段作为新生肽链折叠的模型，用同核二维核磁共振谱和远紫外圆二色谱研究了它们的溶液构象特征。

Micrococcal nuclease hypersensitive DNA fragments were either cloned directly, or mapped onto the genome by hybridization with oligo-nucleotide probes on a 244K Agilent array-CGH chip. The array-CGH mapping was confirmed for nuclease sensitivity by PCR after MNase digestion and by Southern blot analysis.
