The indicated plasmid combinations were used for the protein-protein interaction test according to the manufacturers instructions (Clontech, Phenotype characterization In vitro pollen germination was conducted in a Petri dish containing solid PGM [1% low melting point agarose (w/v), 18% sucrose (w/v), 0.01% boric acid (w/v), 1 mM CaCl 2 , 1 mM Ca(NO 3 ) 2 , and 1 mM MgSO 4 , adjusted to pH 7.5 using 0.2 M KOH] at 28 C, following a protocol modified from Boavida and McCormick (2007) 67
At the molecular level, 5-amino-1MQ functions as a competitive inhibitor of NNMT, demonstrating remarkable potency with an IC of 1.2 0.1 M under standard assay conditions (50 M SAM, 100 M nicotinic acid). This represents a dramatic 10-fold improvement over the parent compound 1-methylquinolinium, achieved through strategic amino group substitution that enhances binding affinity to the NNMT active site. The compound's mechanism centers on preventing the methylation of nicotinamide to 1-methylnicotinamide (1-MNA), thereby preserving nicotinamide for recycling back to NAD+ through the salvage pathway. This intervention effectively blocks what researchers have termed the "NNMT metabolic drain" a process that simultaneously depletes NAD+ precursors and consumes cellular methylation capacity
