General annotation (Comments)

Function

Catalyzes the condensation of nicotinamide with 5-phosphoribosyl-1-pyrophosphate to yield nicotinamide mononucleotide, an intermediate in the biosynthesis of NAD. It is the rate limiting component in the mammalian NAD biosynthesis pathway By similarity.

Catalytic activity

Nicotinamide D-ribonucleotide + diphosphate = nicotinamide + 5-phospho-alpha-D-ribose 1-diphosphate.

Pathway

Cofactor biosynthesis; NAD(+) biosynthesis; nicotinamide D-ribonucleotide from 5-phospho-alpha-D-ribose 1-diphosphate and nicotinamide: step 1/1.

Subunit structure

Homodimer. Ref.4

Subcellular location

Cytoplasm. Nucleus Ref.1.

Tissue specificity

Expressed in various tissues. At the highest level in liver and at the second highest in heart. The amount is higher in heart than in lung. Ref.1

Sequence similarities

Belongs to the NAPRTase family.
