WebMar 30, 2024 · The availability of oxygen and adenylates serve as metabolic checkpoints of the cell cycle, whereas genotoxic stress triggers a reprogramming of mitochondrial metabolism to ensure energy sufficiency during quiescence. Hence, there is a bi-directional regulatory relationship between the cell cycle and metabolism (Kaplon et al., 2015 ). WebIn aconitase, the Fe–S cluster binds aconitate at the one Fe centre that lacks a thiolate ligand. The cluster does not undergo redox, but serves as a Lewis acid catalyst to convert citrate to isocitrate. In radical SAM enzymes, the cluster binds and reduces S-adenosylmethionine to generate a radical, which is involved in many biosyntheses. [5]
