2.4.2.19	additional information	key enzyme of NAD+ biosynthesis	
2.4.2.19	additional information	enzyme of the kynurenine pathway	
2.4.2.19	additional information	key enzyme in NAD+ biosynthesis, also plays an important role in ensuring nicotinic acid available for the synthesis of defensive pyridine alkaloids	
2.4.2.19	additional information	intermediary enzyme in the de novo NAD biosynthetic pathway	
2.4.2.19	additional information	the recruitment of this gene for growth on phthalate gives Burkholderia cepacia an advantage over other phthalate-degrading bacteria in the environment	
2.4.2.19	additional information	key enzyme in catabolism of quinolinate. Quinolinate acts as a most potent endogenous exitotoxin to neurons. Elevation of quinolinate levels in the brain has been linked to the pathogenesis of neurodegenerative disorders
