  • 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......閱讀全文

    蛋白質結構預測(protein-structure-prediction)

    一種生物體的基因組規定了所有構成該生物體的蛋白質,基因規定了組成蛋白質的氨基酸序列。雖然蛋白質由氨基酸的線性序列組成,但是,它們只有折疊成特定的空間構象才能具有相應的活性和相應的生物學功能。了解蛋白質的空間結構不僅有利于認識蛋白質的功能,也有利于認識蛋白質是如何執行其功能的。確定蛋白質的結構對于生物

    蛋白質二級結構預測(protein-secondary-structure-prediction)

    蛋白質二級結構的預測開始于20世紀60年代中期。二級結構預測的方法大體分為三代,第一代是基于單個氨基酸殘基統計分析,從有限的數據集中提取各種殘基形成特定二級結構的傾向,以此作為二級結構預測的依據。第二代預測方法是基于氨基酸片段的統計分析,使用大量的數據作為統計基礎,統計的對象不再是單個氨基酸殘基,而

    蛋白質二級結構(protein-secondary-structure)預測軟件

    蛋白質二級結構的預測通常被認為是蛋白結構預測的第一步,二級結構是指α螺旋和β折疊等規則的蛋白質局部結構元件。不同的氨基酸殘基對于形成不同的二級結構元件具有不同的傾向性。按蛋白質中二級結構的成分可以把球形蛋白分為全α蛋白、全β蛋白、α+β蛋白和α/β蛋白等四個折疊類型。預測蛋白質二級結構的算法大多以已

    蛋白質三級結構(tertiary-structure-of-protein)的預測軟件

    由于用X光晶體衍射和NMR核磁共振技術測定蛋白質的三維結構,以及用生化方法研究蛋白質的功能效率不高,無法適應蛋白質序列數量飛速增長的需要,因此近幾十年來許多科學家致力于研究用理論計算的方法預測蛋白質的三維結構和功能,經過多年努力取得了一定的成果。蛋白質三維結構的預測方法通常包括:同源性建模和從頭開始
