Size matters for polyP to clot ---------------------------------------------------------------------------------------------------------------Usha R. Pendurthi THE UNIVERSITY OF TEXAS HEALTH SCIENCE CENTER AT TYLER All living organisms contain polyphosphate—a linear polymer of inorganic phosphate. Depending on where they are derived, the polymers exist in different lengths. In this issue of Blo...
Diadenosine pentaphosphate and diadenosine hexaphosphate have been isolated in human platelets and have been postulated to play an important role in the control of vascular tone. Here we describe the isolation and identification of diadenosine heptaphosphate from human platelets. Dinucleoside polyphosphates were concentrated by affinity chromatography from a nucleotide-containing fraction from ...
Luciferase catalyzes the preferential synthesis of adenosine(5')tetraphospho(5')nucleoside (Ap4N) in the presence of luciferin (LH2), adenosine 5'-[gamma-thio]triphosphate (ATP[gamma S]) and NTP (other than ATP), with very low, or undetectable synthesis of Ap4A or Np4N, because ATP[gamma S] is a good adenylyl donor for the formation of the E-LH2-AMP complex, but a poor adenylyl acceptor from th...
