Supplementary information

QPRT also known as Nicotinate-nucleotide pyrophosphorylase [carboxylating] or Quinolinate phosphoribosyltransferase functions as an important enzyme in the kynurenine pathway a metabolic pathway leading to the production of nicotinamide adenine dinucleotide (NAD+). The enzyme catalyzes the conversion of quinolinate to nicotinic acid mononucleotide. QPRT has a molecular mass of approximately 34 kDa. It is expressed in various tissues most notably in the liver kidney and brain.
Biological function summary

QPRT influences the synthesis of NAD+ which is essential for cellular redox reactions and energy metabolism. The enzyme operates as a monomer and does not typically form part of a larger complex. However its activity is important in maintaining NAD+ levels which can impact a wide range of cellular processes such as DNA repair signal transduction and metabolism.

Pathways

QPRT holds a significant role in the kynurenine pathway and NAD+ biosynthesis. This pathway includes several enzymes such as kynurenine 3-monooxygenase and kynureninase which collaboratively contribute to the degradation of tryptophan ultimately affecting the levels of important coenzymes and neurotransmitters. The NAD+ biosynthesis pathway involving QPRT also interacts with pathways for ATP generation connecting with other metabolic processes.

QPRT's malfunction links to neurological disorders such as Alzheimer's disease due to its role in NAD+ metabolism and potential effects on neuronal health and energy supply. Additionally alterations in QPRT activity have associations with liver diseases considering its expression and function in metabolic pathways within hepatic tissues. Interaction with proteins like kynurenine aminotransferase highlights its involvement in maintaining metabolic balance within these conditions.
