Last month, the ATP switched from a United States-based testing company to a Swedish firm, in part because of its advanced blood-testing capabilities.
Once activated, it switches on catabolic pathways that generate adenosine triphosphate (ATP), while switching off ATP-consuming anabolic processes.
Once activated, AMPK switches on catabolic pathways that generate ATP, while switching off ATP-requiring processes not essential for short-term cell survival, including cell growth and proliferation (Hardie, 2007).
Once activated, the system switches on catabolic pathways that generate ATP while switching off ATP-consuming processes (Hardie, 2007b).
Once activated, AMPK switches on catabolic pathways that generate ATP while switching off ATP-consuming processes, such as cell growth and proliferation, and activating autophagy.
Thus the ATP switch model proposes that the conformational changes associated with ATP binding are sufficient to switch the substrate-binding site from high to low affinity, thus releasing the substrate on the other side of the membrane [ 54].
ATP-binding and domain dimerization also initiates a cascade of protein protein assembly events, a common feature of the dual ATP switches.
Once activated, AMPK switches on catabolic pathways that generate ATP while switching off anabolic pathways and other ATP-requiring processes such as progress through the cell cycle [ 1].
AMPK switches on catabolic pathways that generate ATP, while switching off biosynthetic pathways and other processes that consume ATP, and hence has a key role in maintaining energy balance both at the single cell and the whole body levels [ 2, 9].
AMPK plays therefore a dual role, first by providing metabolites that can serve as substrates for ATP synthesis, thereby increasing ATP availability, and second by decreasing ATP consumption and minimizing ATP "wastage" through switching off defined ATP-consuming processes (Fig. 2).
