NADSYN1

Nicotinamide adenine dinucleotide (NAD) is a coenzyme in metabolic redox reactions, a precursor for several cell signaling molecules, and a substrate for protein posttranslational modifications. NAD synthetase (EC 6.3.5.1) catalyzes the final step in the biosynthesis of NAD from nicotinic acid adenine dinucleotide (NaAD).[supplied by OMIM

Full Name

NAD synthetase 1

Function

Catalyzes the final step of the nicotinamide adenine dinucleotide (NAD) de novo synthesis pathway, the ATP-dependent amidation of deamido-NAD using L-glutamine as a nitrogen source.

Involvement in disease

Vertebral, cardiac, renal, and limb defects syndrome 3 (VCRL3):
An autosomal recessive, lethal disorder characterized by severe cardiac and renal anomalies, including hypoplastic or absent left ventricle, transposition of the great arteries, absent pulmonary trunk, and hypoplastic or absent kidneys. Patients also exhibit vertebral segmentation defects and shortening of the proximal long bones or micromelia. Death occurs in early infancy.
