2,5-diamino-6-hydroxy-4-(5-phosphoribosylamino)pyrimidine is a metabolite in the purine metabolism, formed by the hydrolysis of GTP by GTP cyclohydrolase II. Alternatively two separate enzymes can carry out this reaction, initially GTP cyclohydrolase IIa hydrolyses the 8,9 bond to form 2-Amino-5-formylamino-6-(5-phospho-D-ribosylamino)pyrimidin-4(3H)-one, followed by de-formylation by 2-amino-5-formylamino-6-ribosylaminopyrimidin-4(3H)-one 5'-monophosphate deformylase. 2,5-diamino-6-hydroxy-4-(5-phosphoribosylamino)pyrimidine is deaminated by Diaminohydroxyphosphoribosylaminopyrimidine deaminase to form 5-amino-6-(5-phosphoribosylamino)uracil.
Sylvy Kornberg née Sylvia Ruth Levy (1917–1986) was an American biochemist who carried out research on DNA replication and polyphosphate synthesis. She discovered and characterized polyphosphate kinase (PPK), an enzyme that helps build long chains of phosphate groups called polyphosphate (PolyP) that play a variety of metabolic and regulatory functions. She worked closely with her husband and research partner, Arthur Kornberg, contributing greatly to the characterization of DNA polymerization that earned him the 1959 Nobel Prize in Physiology or Medicine.
Bernard Leonard (Bernie) Horecker (1914–2010) was an American biochemist known for work on the pentose phosphate pathway, and for cellular regulation in general.
