Genetic recombination is a basic cellular process required for altering genome structure. The RecA protein of Escherichia coli has a central role in homologous recombination, and a eukaryotic protein with similar properties has been discovered in the yeast Saccharomyces cerevisiae. Unexpectedly, this RecA-like protein has additional biochemical activities, and its function may not be restricted to recombination.
基因重组是改变基因组结构所需的基本细胞过程。大肠杆菌的RecA蛋白在同源重组中起核心作用,并且在酿酒酵母中发现了具有类似性质的真核蛋白。出乎意料的是,这种类RecA蛋白具有额外的生化活性,其功能可能不限于重组。
