Machines of protein destruction-including energy-dependent proteases and disassembly chaperones of the AAA(+) ATPase family-function in all kingdoms of life to sculpt the cellular proteome, ensuring that unnecessary and dangerous proteins are eliminated and biological responses to environmental change are rapidly and properly regulated. Exciting progress has been made in understanding how AAA(+) machines recognize specific proteins as targets and then carry out ATP-dependent dismantling of the tertiary and/or quaternary structure of these molecules during the processes of protein degradation and the disassembly of macromolecular complexes.
蛋白质破坏机器——包括能量依赖型蛋白酶和AAA(+)ATP酶家族的拆卸伴侣蛋白——在所有生命王国中发挥作用,塑造细胞蛋白质组,确保清除不必要和危险的蛋白质,并迅速且适当地调节对环境变化的生物学反应。在理解AAA(+)机器如何识别特定蛋白质作为靶标,然后在蛋白质降解和大分子复合物拆卸过程中对这些分子的三级和/或四级结构进行ATP依赖型拆解方面,已经取得了令人兴奋的进展。
