2021年2月22日 · In the numerous molecular recognition and catalytic processes across biochemistry involving adenosine triphosphate (ATP), the common bioactive form is its magnesium chelate, ATP·Mg 2+. In aqueous solution, two chelation geometries predominate, distinguished by bidentate and tridentate Mg 2+ –phosphate coordination.

腺苷5γ-三磷酸腺苷(atp)是体内能量储存和代谢的中心成分。 ATP应用于许多细胞过程、呼吸、生物合成反应、运动和细胞分裂。 ATP是许多激酶的底物，这些激酶参与细胞信号和腺苷酸环化酶(s)，产生第二个信使 cAMP。

2024年8月9日 · Our results demonstrate that Mg 2+ induces a conformational rearrangement of the substrates (ATP and ADP), resulting in a 30° adjustment of the angle essential for reversible phosphoryl transfer, thereby optimizing it for catalysis.

In general, Mg2+ interacts with substrates through inner sphere coordination, stabilising anions or reactive intermediates, also including binding to ATP and activating the molecule to nucleophilic attack (wiki)

2024年5月27日 · We show the applicability of the approach to biomolecules in a complex environment, exploring site-specific information on the interaction of adenosine triphosphate in the aqueous phase (ATP (aq)) with magnesium (Mg 2+(aq)), highlighting the synergy brought about by the simultaneous analysis of different regions in the photoelectron spectrum.

Adenosine Triphosphate Magnesium refers to a compound composed of ATP and magnesium sulfate, commonly used in various scientific experiments and procedures. You might find these chapters and articles relevant to this topic. Maruda Shanmugasundaram, ... Frank T. Robb.

1999年10月8日 · These novel findings indicate that Mg (2+) plays a pivotal role in transition state formation during ATP synthesis catalyzed by ATP synthases, a role that involves both its preferential coordination with P (i) and the repositioning of the P-loop to bring the nonpolar alanine 158 into the catalytic pocket.

2024年11月21日 · In cells, adenosine triphosphate (ATP) and guanosine triphosphate (GTP) molecules typically form tricoordinated or bicoordinated ATP·Mg 2+ or GTP·Mg 2+ complexes with Mg 2+ ions and bind to proteins, participating in …

For example, adenosine triphosphate (ATP), the main source of energy in cells, must bind to a magnesium ion in order to be biologically active. What is called ATP is often actually Mg-ATP. [5] As such, magnesium plays a role in the stability of all polyphosphate compounds in the cells, including those associated with the synthesis of DNA and RNA.
