amphipathic,英語單詞,主要用作形容詞,作形容詞時譯為“兩親的(等於amphiphilic);兩性分子的;親水脂性的”。
兩親結構(Amphipathic structure)是指分子同時具有親水表面和疏水表面的結構,常見於脂類分子及某些蛋白質結構域。這類分子通過不同性質的表面參與生物膜形成,蛋白質兩親螺旋的特徵表現為一個表面帶電荷,另一表面呈電中性。華南理工大學團隊通過合成由親水碳60衍生物與疏水寡聚芴片段構成的巨型脂質分子,重現了天然脂質...
兩親螺旋(amphipathic helix)是2008年公布的生物化學與分子生物學名詞。該結構在蛋白質功能中具有多樣性作用:可溶性鳥苷酸環化酶α1亞基431-464殘基通過兩親α-螺旋介導異源二聚體形成,其中Leu463突變會破壞活性中心結構;皰疹病毒Tip蛋白的膜近端兩親螺旋通過結合帶負電荷脂質誘導脂質體管狀化,並與跨膜結構域協同...
雙親媒性分子(amphipathic molecule)是指分子中同時存在親近某種物質的結構與疏遠該物質結構的化合物。其典型特徵為同一分子內兼具兩種相反性質的組成部分。磷脂分子是此類分子的代表,其結構由親水性的頭部基團與疏水性的尾部鏈狀結構共同構成。概念:分子既含親近某種物質的結構又含疏遠這種物質的結構, 這樣的分子稱為...
位於肽鏈C端,是一種兩親性α螺旋(amphipathic α helix),螺旋一側有一系列疏水性胺基酸形成疏水面(hydrophobic surface),是形成二聚體結構的結合面。兩個單體通過亮氨酸拉鏈結合形成二聚體,二聚體中兩段亮氨酸拉鏈疏水面平行相對,相互纏繞形成左手捲曲螺旋(coiled coil)。亮氨酸拉鏈一級結構的一個顯著特徵是...
基序由40~50個胺基酸組成,含有2個兩親的(amphipathic,既有極性基也有非極性基)。螺旋,由2個長度不等的連線區(環)相連。通過兩條螺旋對應位置上的疏水性胺基酸殘基之間的相互作用,可以生成同源二聚體或異源二聚體。每個螺旋區長15~16個胺基酸,其中有幾個胺基酸殘基是保守的。兩個螺旋區之間的環使兩個螺旋區...
S2具有三段兩性的七價重複序(amphipathic heptad repeatsequence),每個區域都有形成捲曲螺旋結構的傾向。因此我們推測,S1與受體結合釋放的能量使S2融合肽暴露出來,三段預測的螺旋區域(helical region)變為捲曲結構(coiled—coil structure),進而使病毒外膜同靶細胞外膜充分接近。MHV JHM毒株S蛋白的行為表明可能存在另外一...
