Journal of Limnology, 2011 The growth of Microcystis aeruginosa and Chlorella pyrenoidosa in three dissolved organic phosphorus sources (glucose-1- phosphate, adenosine triphosphate, cyclic-adenosine monophosphate) were studied in cultures separated by a dialysis membrane. Results

Model for the unidirectional motion of a dynein molecule [PDF]
Phys. Rev. E 77, 051916 (2008), 2008 Cytoplasmic dyneins transport cellular organelles by moving on a microtubule filament. It has been found recently that depending on the applied force and the concentration of the adenosine triphosphate (ATP) molecules, dynein's step size varies. Based on these studies, we propose a simple model for dynein's unidirectional motion taking into account the

Optical Aptasensors for Adenosine Triphosphate
Theranostics, 2016 Nucleic acids are among the most researched and applied biomolecules. Their diverse two- and three-dimensional structures in conjunction with their robust chemistry and ease of manipulation provide a rare opportunity for sensor applications. Moreover, their high biocompatibility has seen them being used in the construction of in vivo assays.

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 ...

Coupling of actin hydrolysis and polymerization: Reduced description with two nucleotide states [PDF]
EPL 89, 38010 (2010), 2011 The polymerization of actin filaments is coupled to the hydrolysis of adenosine triphosphate (ATP), which involves both the cleavage of ATP and the release of inorganic phosphate. We describe hydrolysis by a reduced two-state model with a cooperative cleavage mechanism, where the cleavage rate depends on the state of the neighboring actin protomer in a

Effect of adenosine or adenosine triphosphate on antidromic tachycardia
Journal of the American College of Cardiology, 1994 This study was designed to determine the effect of adenosine or adenosine triphosphate (ATP) on antidromic tachycardia.Adenosine and adenosine triphosphate are useful for differential diagnosis of wide QRS tachycardia. It has been believed that tachycardia termination caused by these agents is due to the preferential depressive effect on the ...

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.
