Structural insights into Plasmodium falciparum nicotinamide mononucleotide adenylyltransferase: oligomeric assembly

The biochemical pathways involved in nicotinamide adenine dinucleotide (NAD) biosynthesis converge at the enzymatic step catalysed by nicotinamide mononucleotide adenylyltransferase (NMNAT, EC: 2.7.7.1). The majority of NMNATs are assembled into homo-oligomeric states that comprise 2-6 subunits. Recently, the NMNAT of Plasmodium falciparum (PfNMNAT) has been identified as a pharmacological target. The enzymatic characterisation, cellular location, and tertiary structure of the PfNMNAT protein have been reported. Nonetheless, its quaternary structure remains to be explored. The present study de...
