Molecular basis of rabbit N-acetyltransferase (NAT) polymorphism

NAT 2 ( N - acetyltransferase 2 ( arylamine N - acetyltransferase ) )

NAT 1 ( N - acetyltransferase 1 ( arylamine N - acetyltransferase ) )

The human NAT1 gene has nine exons. The coding region is located in exon 9 and spans 870 bp. Diverse NAT1 transcripts have been reported and two promoters exist. The first promoter, designated as P1 is located in the 5' flanking region of exon 1 and controls two major (a1 and a2) transcripts. The second promoter is located upstream of exon 4 and give rise to at least five (b1 to b5) different t...

Molecular and genetic analyses of arylamine N-acetyltransferase polymorphism of rabbit liver.

A cDNA clone encoding the full coding region of polymorphic arylamine N-acetyltransferase was isolated from rabbit liver and expressed in Chinese hamster ovary cells. The expressed enzyme acetylated 2-aminofluorene, procainamide, sulfamethazine, and p-aminobenzoic acid at equivalent rates. N-Acetyltransferase activity was measured in 17 rabbits from an inbred colony which were classified into r...

A long-lived luminescent probe to sensitively detect arylamine N-acetyltransferase (NAT) activity of cells.

Arylamine N-acetyltransferase (NAT) is an important phase II metabolizing enzyme that influences drug efficacy and adverse effects. Here, we report a long-lived luminescent lanthanide complex as a probe for NAT, employing an intraligand photoinduced electron transfer strategy. The probe shows approximately 100-fold increase of luminescence upon N-acetylation catalyzed by NAT, with relatively hi...

N-acetyltransferase-2 polymorphism in Parkinson's disease: the Rotterdam study.

The N-acetyltransferase-2 gene (NAT-2) has been associated with Parkinson's disease. The genotype associated with slow acetylation has been reported to be increased in patients with Parkinson's disease. Three mutant alleles M1, M2, and M3 of NAT-2 were investigated in 80 patients with idiopathic Parkinson's disease and 161 age matched randomly selected controls from a prospective population bas...
