Purine biosynthesis occurs in the cytosol of all cells. The purine ring is built up in a series of 11 enzyme catalysed steps. Each enzyme is oligomeric, which means it contains several monomers.

Purinergic signaling, mediated by extracellular purines such as ATP and adenosine, plays a role in immune regulation. Targeting purinergic receptors and enzymes involved in purine metabolism is a ...

"We have shown that the de novo purine biosynthetic [DNPB] pathway is carried out by purinosomes consisting of at least nine enzymes acting together synergistically to increase their overall ...

For more than 40 years, scientists have hypothesized the existence of enzyme clusters, or “metabolons,” in facilitating various processes within cells. Using a novel imaging technology combined with ...

Analysis of the transport pathways. ... "These results demonstrate a pharmacologically effective axis between purine metabolism and BRD4-dependent chromatin states," explains study leader Giulio ...
