Overview

Mode of Action (MoA) transfers adenyl group from ATP to nicotinamide mononucleotide and form NAD+
Evidence Expression of Nmnat from Vibrio phage KVP40 enabled the conversion of NMN to NAD⁺ in vitro in the presence of ATP. Co-expression with Nampt reconstituted NAD⁺ from PRPP and nicotinamide, validating functional linkage (ECO_0001096).
MoA Category synthesises and restores essential molecules depleted by bacterial defence
