摘要

金属蛋白是蛋白质组的重要组成部分。它们的结构测定和蛋白质-蛋白质相互作用的研究允许研究金属辅助因子的作用和解释生物物理特征和生物功能。方法是基因组浏览,表达一些有代表性的样品和伴侣蛋白,确定结构(主要是通过核磁共振,通过快速协议),并建立其他同源蛋白的模型。对一些参与铜稳态的蛋白质和某些类型的细胞色素c和铁氧化还原蛋白的结构进行了分析,这些结构反过来又将基因与蛋白质功能联系起来。

Structural genomics on metalloproteins

Metalloproteins constitute a significant share of the proteome. Their structure determination and protein-protein interaction studies allow investigation of the role of metal cofactors and interpretation of the biophysical features and the biological function. The approach is that of genome browsing, expression of a few representative samples and partner proteins, structure determination (mainly by NMR, through quick protocols), and modeling of the other homologous proteins. The analysis of structures which in turn connect genes to protein function is presented for some proteins involved in copper homeostasis and for some classes of cytochromes c and ferredoxins.
