相关研究成果2024年9月6日在线发表于《科学》杂志上,Polytomella线粒体ATP合酶的原位结构与旋转状态,最新IF:63.714 官方网址: https://www.sciencemag.org/ , whereby an electrochemical gradient is established across the inner mitochondrial membrane. The ATP synthase harnesses the energy of the gradient to generate ATP from adenosine diphosphate (ADP) and inorganic phosphate. We determined the structure of ATP synthase within mitochondria of the unicellular flagellate Polytomella by electron cryo-tomography and subtomogram averaging at up to 4.2-angstrom resolution,ATP是通过一系列氧化还原反应产生的, Christina Kunz,imToken钱包下载, ATP is produced by a series of redox reactions,Polytomella ATP合酶形成具有多个相邻行的螺旋阵列, subclassified into 21 substates of the F1 head. The Polytomella ATP synthase forms helical arrays with multiple adjacent rows defining the cristae ridges. The structure of ATP synthase under native operating conditions in the presence of a membrane potential represents a pivotal step toward the analysis of membrane protein complexes in situ.
