Key points: The single ppk gene (No.8) can regenerate the AMP-ATP cycle, crucial for ATP-dependent reactions. Inserting the ppk gene (No.8) into the cr5 site of the E.coli genome achieves expression levels comparable to the pET29a plasmid. The expression level of the ppk gene (No.8...
因此,利用双稳态行为构建的开关(双稳态开关)具备超敏响应特性和抗噪能力,在信号传导和细胞周期调控中发挥着关键作用[4]。在酵母细胞周期中,调控网络通过关键蛋白的磷酸化-去磷酸化循环(Phosphorylation-dephosphorylation cycle,PdP cycle),结合正反馈调...

ATP is a critical molecule found in all living cells and is the energy source for various biological processes, including muscle contraction, nerve impulse propagation, and biochemical synthesis. ATP levels are often measured to determine cellular viability and metabolism, assess mitochondria function and...
Male humpback whales vocalize in the form of songs that can last over half an hour, which are acquired through learning. Language acquisition begins in the juvenile stage of thewhale's life cycleand evolves over years. Although female whales vocalize, scientists are uncertain why they do not si...

The ?ndings suggest that nutrient uptake in cancer cells is limited by ATP and satis?es energy requirements other than ATP production.这些发现表明癌细胞中营养的摄取受ATP的限制，可满⾜ATP产⽣之外的能量需求。Mounting evidence suggests that cancer cells engage in a unique metabolic program that ...
Tissues derive ATP from two pathways—glycolysis and the tricarboxylic acid (TCA) cycle coupled to the electron transport chain. Most energy in mammals is produced via TCA metabolism1. In tumours, however, the absolute rates of these pathways remain unclear. Here we optimize tracer infusion approa...

ATP synthaseis a ubiquitousenzymethat is largely conserved across the kingdoms of life. This conservation is in accordance with its central role in chemiosmotic energy conversion, a pathway utilized by far by most living cells. On the other hand, in particular pathogenic bacteria whilst employing AT...
