在生物化学中，三磷酸腺苷(Adenosine triphosphate, ATP)是一种核苷酸，作为细胞内能量传递的“分子通货”，储存和传递化学能。ATP在核酸合成中也具有重要作用。ATP是三磷酸腺苷的英文名称缩写。ATP分子的结构是可以简写成A-P~P~P，其中A代表腺苷，P代表磷酸基团，～代表一种特殊的化学键，叫做高能磷酸键...
ATP is an unstable molecule in unbuffered water, in which it hydrolyses to ADP and phosphate. This is because the strength of the bonds between the phosphate groups in ATP is less than the strength of the hydrogen bonds (hydration bonds), between its products (ADP and phosphate), and water...
ATP is anucleoside, in this case adenosine, with three phosphate groups attached to it. This actually makes it anucleotide, as a nucleoside is apentosesugar (eitherriboseordeoxyribose) combined with a nitrogenous base (i.e., adenine, cytosine, guanine, thymine or uracil), whereas a nucleotide...
BATP consists the nitrogenous base, adenine and the sugar, deoxyribose. CATP is a nucleotide which contains a chain of three phosphate groups bound to ribose sugar. DThe nitrogenous base of ATP is the actual power source.Submit Question 3 - Select OneRead...
The p97-ND1L hexamer (residues 1–480) is ATPase active6 and contains only signals from D1; the corresponding spectra of full-length p97 are shown in lighter hues. Right: the observation of multiple weaker signals (orange fit) is ascribed to phosphate ions in chemically distinct environments...
The ion was placed at a close distance (2 ) from the charged oxygen atoms of the beta and gamma phosphate groups of the 3 negatively charged ATP analogue molecules. Analysis of the results revealed the distribution of inter-proton distances H8–H1 ′ and H8–H2 ′ versus the torsion angle...
(typically part of the conserved A-loop) and S565 of BmrD interacts with the adenine ring of ATP. The phosphate groups are coordinated by residues G374, S375, G376, and K377 from Walker A of BmrC, Q419 from the Q-loop of BmrC, and S568 and G570 of BmrD (Supplementary Fig.13b...
ATP is anothersmall moleculethat stimulates 5-LOX activity by direct binding. The stimulatory activity of adenosine nucleotides increases with the number of phosphate groups (AMP<ADP<ATP) and does not involve ATPhydrolysis(reviewed in[3,52]). Although the 5-LOX structure does not contain a known...
Between β3 and α5 (residues 321–334) the loop corresponding to the so-called “ATP lid,” is fully defined in electron density (Fig. 1E), albeit showing higher than average B factors, both on side chains and the main chain. The ATP lid contains some residues that interact with the...
Metabolism - ATP Formation, Enzymes, Energy: The second stage of glucose catabolism comprises reactions [6] through [10], in which a net gain of ATP is achieved through the oxidation of one of the triose phosphate compounds formed in step [5]. One molecu
