Adenosine triphosphate stimulates Aquifex aeolicus MutL endonuclease activity. [PDF]

PLoS ONE, 2009
BACKGROUND:Human PMS2 (hPMS2) homologues act to nick 5' and 3' to misincorporated nucleotides during mismatch repair in organisms that lack MutH. Mn(++) was previously found to stimulate the endonuclease activity of these homologues. ATP was required for

Application of the adenosine triphosphate sensitivity assay in infantile vascular anomalies

BMC Pediatrics, 2020
Background The term vascular anomalies include various vascular tumors and vascular malformations, among them infantile hemangiomas and capillary malformations are the most well-known associated diseases in early ages. Multiple drugs have been introduced

New Algorithm of Stress Echocardiography with Adenosine Triphosphate

Вестник рентгенологии и радиологии, 2020
Objective. Submaximal myocardial hyperemia is known not to be achieved in 16-18% of cases during cardiac stress tests and monotonic intracubital administration of adenosine triphosphate (ATP) at a dose of 140-160 pg/kg/min.

Purinergic Signaling in Pulmonary Inflammation

Frontiers in Immunology, 2019
Purine nucleotides and nucleosides are at the center of biologic reactions. In particular, adenosine triphosphate (ATP) is the fundamental energy currency of cellular activity and adenosine has been demonstrated to play essential roles in human ...

Visual and Plasmon Resonance Absorption Sensor for Adenosine Triphosphate Based on the High Affinity between Phosphate and Zr(IV)

Sensors, 2016
Zr(IV) can form phosphate and Zr(IV) (–PO32−–Zr4+–) complex owing to the high affinity between Zr(IV) with phosphate. Zr(IV) can induce the aggregation of gold nanoparticles (AuNPs), while adenosine triphosphate(ATP) can prevent Zr(IV)-induced ...

Phosphorylation of Myosin by Adenosine Triphosphate [PDF]

Nature, 1948
THE study of the interaction between actomyosin and adenosine triphosphate has hitherto given evidence of physical changes in the protein and of its enzymic activity. Very little was known, however, of chemical changes in the protein molecule accompanying the physical effects.
