What rhymes with atp phosphoribosyltransferase?
at·p phos·pho·ri·bo·syl·trans·ferase

In enzymology, an ATP phosphoribosyltransferase is an enzyme that catalyzes the chemical reaction Thus, the two substrates of this enzyme are 1--ATP and diphosphate, whereas its two products are ATP and 5-phospho-alpha-D-ribose 1-diphosphate. This enzyme belongs to the family of glycosyltransferases, specifically the pentosyltransferases. The systematic name of this enzyme class is 1--ATP:diphosphate phospho-alpha-D-ribosyl-transferase. Other names in common use include phosphoribosyl-ATP pyrophosphorylase, adenosine triphosphate phosphoribosyltransferase, phosphoribosyladenosine triphosphate:pyrophosphate, phosphoribosyltransferase, phosphoribosyl ATP synthetase, phosphoribosyl ATP:pyrophosphate phosphoribosyltransferase, phosphoribosyl-ATP:pyrophosphate-phosphoribosyl phosphotransferase, phosphoribosyladenosine triphosphate pyrophosphorylase, and phosphoribosyladenosine triphosphate synthetase. This enzyme catalyses the first step in the biosynthesis of histidine in bacteria, fungi and plants. It is a member of the larger phosphoribosyltransferase superfamily of enzymes which catalyse the condensation of 5-phospho-alpha-D-ribose 1-diphosphate with nitrogenous bases in the presence of divalent metal ions.
