We also used this mutant (SMdC) as a host to generate two types of lacZ transcriptional reporter fusion strains to assay the promoter activity of QS-controlled target genes, comDE and nlmAB, in response to addition of CSP. The lacZ reporter strain, SMdC-pYH2 (PcomDE::lacZ, comC ?, Specr, Kanr), along with its background control strain SMdC-pSL (comC ?, Specr, Kanr) we......閱讀全文

如果你最近還沒有為你的貓咪做檢查，那你也可能不知道你的貓咪可能感染了艾滋病毒。貓免疫缺陷病毒肯能會引起貓咪致病，其癥狀類似感染HIV病毒后的癥狀。但是科學家認為這是研究抗HIV新藥的一種契機。 貓咪會怎么幫助人們抗擊艾滋病呢？不管是貓免疫缺陷病毒（FIV)還是人免疫缺陷病毒都會依賴一種稱為整合
Structure封面文章：解密白內障的形成
白內障是致盲的第一殺手，目前世界上有近兩千萬人受到它的影響。日前，加州大學Irvine分校的科學家們取得了重要成果，揭開了白內障的形成機制，這一成果將有望幫助人們為白內障患者恢復視力。這項研究作為封面文章刊登在十二月的Structure雜志上。 “我們的研究闡述了白內障形成的分子機制，這一
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
