Barnase基因
웹2024년 12월 1일 · barnase具有强烈的杀菌作用，因此该基因的表达能造成宿主细胞的死亡。barstar是解淀粉芽孢杆菌基因组中barnase的特异性抑制蛋白，其氨基酸序列如seqidno.3所示，其产物能与barnase以1:1特异性结合形成一种稳定的复合物，从而导致barnase丧失活性。 웹本发明公开了一种DNA分子、一种重组载体、一种细胞和一种植物。本发明还公开了一种有效防止转基因植物花粉逃逸的方法，包括如下步骤：步骤一、将DNA分子构建到表达载体上得到带有DNA分子的重组载体；步骤二、将重组载体转化到植物细胞中，筛选、培养得到含有DNA分子的转基因植株。本发明 ...

Barnase (a portmanteau of "BActerial" "RiboNucleASE") is a bacterial protein that consists of 110 amino acids and has ribonuclease activity. It is synthesized and secreted by the bacterium Bacillus amyloliquefaciens, but is lethal to the cell when expressed without its inhibitor barstar. The inhibitor binds to … 더 보기 Barnase has no disulfide bonds, nor does it require divalent cations or non-peptide components to fold. This simplicity, in combination with its reversible folding transition, means that barnase has been extensively studied in … 더 보기 Barnase catalyzes hydrolysis at diribonucleotide GpN sites.
