为探究 MutS 2 在同源重组及核糖体循环中的作用机制，研究人员开展了关于 MutS 2 的研究。他们发现 ATP 结合使 MutS 2 钳状结构闭合，且影响其与不同 DNA 的结合。这一成果为相关机制研究提供了关键线索。 MutS 2 可识别分支 DNA 结构，对同源重组（homologous ...

Scientists at Goethe University uncover how the oldest enzyme in cellular respiration functions – opening the door to ...

The bacterial protein identified by the team, which they have named BeeR, has a similar function to actin – the most abundant protein in the majority of human cells. In the presence of a chemical ...

A team of scientists have elucidated an ancient mechanism of cellular respiration. To that end, they studied bacteria that feed on the gases carbon dioxide and hydrogen, and turn them into acetic acid ...

Ancient microbes illustrate a particular kind of respiration in which carbon dioxide and hydrogen are combined to form acetic ...

Actin can also break down ATP, which triggers the filaments to disassemble. Bacteria have similar proteins to actin that form filaments in the presence of ATP and help to control cell shape and ...

Animals, plants and many other living organisms inhale oxygen to "burn" (oxidize) compounds like sugar into CO2 and water—a ...

For the first time, researchers have filmed in real time the disassembly of DNA at the atomic scale. This strand separation ...
