StructureofMitochondria
The cytoplasm of nearly all eukaryotic cells contain mitochondria, although there is at least one exception, the protist Chaos (Pelomyxa) carolinensis. They are especially abundant in cells and parts of cells that are associated with active processes. For example, in flagellated protozoa or in mammalian sperm, mitochondria are concentrated around the base of the flagellum or flagella. In cardiac muscle, mitochon......阅读全文

白内障是致盲的第一杀手,目前世界上有近两千万人受到它的影响。日前,加州大学Irvine分校的科学家们取得了重要成果,揭开了白内障的形成机制,这一成果将有望帮助人们为白内障患者恢复视力。这项研究作为封面文章刊登在十二月的Structure杂志上。 “我们的研究阐述了白内障形成的分子机制,这一
蛋白质结构预测(protein-structure-prediction)
一种生物体的基因组规定了所有构成该生物体的蛋白质,基因规定了组成蛋白质的氨基酸序列。虽然蛋白质由氨基酸的线性序列组成,但是,它们只有折叠成特定的空间构象才能具有相应的活性和相应的生物学功能。了解蛋白质的空间结构不仅有利于认识蛋白质的功能,也有利于认识蛋白质是如何执行其功能的。确定蛋白质的结构对于生物

蛋白质二级结构预测(protein-secondary-structure-prediction)
蛋白质二级结构的预测开始于20世纪60年代中期。二级结构预测的方法大体分为三代,第一代是基于单个氨基酸残基统计分析,从有限的数据集中提取各种残基形成特定二级结构的倾向,以此作为二级结构预测的依据。第二代预测方法是基于氨基酸片段的统计分析,使用大量的数据作为统计基础,统计的对象不再是单个氨基酸残基,而
蛋白质二级结构(protein-secondary-structure)预测软件
蛋白质二级结构的预测通常被认为是蛋白结构预测的第一步,二级结构是指α螺旋和β折叠等规则的蛋白质局部结构元件。不同的氨基酸残基对于形成不同的二级结构元件具有不同的倾向性。按蛋白质中二级结构的成分可以把球形蛋白分为全α蛋白、全β蛋白、α+β蛋白和α/β蛋白等四个折叠类型。预测蛋白质二级结构的算法大多以已
