Quinolinate phosphoribosyl transferase (QAPRTase or QPRTase), also called nicotinate-nucleotide pyrophosphorylase, is involved in the de novo synthesis of NAD in both prokaryotes and eukaryotes. It catalyses the reaction of quinolinic acid (QA) with 5-phosphoribosyl-1-pyrophosphate (PRPP) in the presence of Mg2+ to produce nicotinic acid mononucleotide (NAMN), pyrophosphate and carbon dioxide. QPRTase functions as a homodimer with two active sites, each formed by the C-terminal region of one subunit and the N-terminal region of the other.

It catalyzes the reaction of quinolinic acid with 5-phosphoribosyl-1-pyrophosphate (PRPP) in the presence of Mg2+ to give rise to nicotinic acid mononucleotide (NaMN), pyrophosphate and carbon dioxide. The QA substrate is bound between the C-terminal domain of one subunit, and the N-terminal domain of the other. The C-terminal domain has a 7 beta-stranded TIM barrel-like fold.

Phosphoribosyltransferase (PRTase) type II; This family contains two enzymes that play an important role in NAD production by either allowing quinolinic acid (QA) , quinolinate phosphoribosyl transferase (QAPRTase), or nicotinic acid (NA), nicotinate phosphoribosyltransferase (NAPRTase), to be used in the synthesis of NAD. QAPRTase catalyses the reaction of quinolinic acid (QA) with 5-phosphoribosyl-1-pyrophosphate (PRPP) in the presence of Mg2+ to produce nicotinic acid mononucleotide (NAMN), pyrophosphate and carbon dioxide, an important step in the de novo synthesis of NAD. NAPRTase catalyses a similar reaction leading to NAMN and pyrophosphate, using nicotinic acid an PPRP as substrates, used in the NAD salvage pathway.

In general, QPRTases are part of the de novo synthesis pathway of NAD in both prokaryotes and eukaryotes. They catalyse the reaction of quinolinic acid (QA) with 5-phosphoribosyl-1-pyrophosphate (PRPP) in the presence of Mg2+ to produce nicotinic acid mononucleotide (NAMN), pyrophosphate and carbon dioxide.

putative molybdenum utilization protein ModD; The gene modD for a member of this family is found with molybdenum transport genes modABC in Rhodobacter capsulatus. However, disruption of modD causes only a 4-fold (rather than 500-fold for modA, modB, modC) change in the external molybdenum concentration required to suppress an alternative nitrogenase. ModD proteins are highly similar to nicotinate-nucleotide pyrophosphorylase (also called quinolinate phosphoribosyltransferase). The function unknown. [Unknown function, General]

superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
