- 요약Mitochondria are the powerhouse of the cell. At the core of this function is the oxidative phosphorylation (OxPhos) system. OxPhos is carried out by five protein complexes, of which complex I (CI) is the largest and serves a pivotal role as the primary gateway for electrons into the OxPhos system. While the structure and function of the CI holoenzyme have been characterized extensively at molecular resolution, the molecular details of the process by which this multimeric complex is assembled remains unclear. In recent years, many key advances in our understanding of CI assembly have been made using a systems biochemistry approach. These advances are detailed in chapter 1 of this dissertation, as well as a general overview of systems biochemistry and other examples of its use in mitochondrial biology.In chapter 2, I describe a systematic mutational analysis for deepening our understanding of CI assembly. By measuring the functional consequence of each single-amino-acid-substitution in the CI assembly factor NDUFAF6, we are able glean insights into its molecular function, identify a strategy to bypass its dysfunction, and provide a resource to help diagnose NDUFAF6-related disease. In chapter 3, I explore the regulation of mitochondrial gene expression in OxPhos assembly using an integrated proteomic and transcriptomic dataset. I also use this dataset to examine the regulation of genes involved in coenzyme Q biosynthesis. Chapter 4 summarizes the major findings of chapter 2-3 and outlines next steps for each project. Altogether, this dissertation illustrates the systems biochemistry approach: starting with systematic, large-scale experiments, generating mechanistic hypotheses, and testing them through targeted biochemistry.
