羧基体是存在于所有蓝藻和一些变形菌中的固定CO2的蛋白质隔室。这些结构是碳同化生物工程的有吸引力的候选者,因为它们浓缩了碳,允许固定反应在接近其最大速率的情况下发生,并且因为它们在不同的生物体中自组装有一套标准的生物部件。最近的发现扩大了我们对羧基体如何组装、分布和维持其新陈代谢的理解。这些研究已经导致在将羧基体和碳浓缩机制工程化到重组生物体中方面取得了实质性进展,着眼于在工业微生物和植物中建立该系统。未来的研究也可能考虑在体外carboxysomes的发现和应用科学的潜力。
Carboxysomes are CO2-fixing protein compartments present in all cyanobacteria and some proteobacteria. These structures are attractive candidates for carbon assimilation bioengineering because they concentrate carbon, allowing the fixation reaction to occur near its maximum rate, and because they self-assemble in diverse organisms with a set of standard biological parts. Recent discoveries have expanded our understanding of how the carboxysome assembles, distributes itself, and sustains its metabolism. These studies have already led to substantial advances in engineering the carboxysome and carbon concentrating mechanism into recombinant organisms, with an eye towards establishing the system in industrial microbes and plants. Future studies may also consider the potential of in vitro carboxysomes for both discovery and applied science.
