Characterization of the human gene encoding alpha-aminoadipate aminotransferase (AADAT).

In mammals, the conversion of alpha-aminoadipate to alpha-ketoadipate by alpha-aminoadipate aminotransferase (AADAT) is an intermediate step in lysine degradation. A gene encoding for alpha-aminoadipate aminotransferase and kynurenine aminotransferase activities had been previously identified in the rat (KAT/AadAT). We identified the human gene (AADAT) encoding for AADAT. It has a 2329 bp cDNA, a 1278 bp open-reading frame, and is predicted to encode 425 amino acids with a mitochondrial cleavage signal and a pyridoxal-phosphate binding site. AADAT is 73% and 72% identical to the mouse and rat orthologs, respectively. The genomic structure spans 30 kb and consists of 13 exons. FISH studies localized the gene to 4q32.2. Two transcripts (approximately 2.9 and approximately 4.7 kb) were identified, with expression highest in liver. Bacterial expression studies confirm that the gene encodes for AADAT activity. The availability of the DNA sequence and enzyme assay will allow further evaluation of individuals suspected to have defects in this enzyme. << Less

Cloning and functional expression of a soluble form of kynurenine/alpha-aminoadipate aminotransferase from rat kidney.
Buchli R., Alberati-Giani D., Malherbe P., Koehler C., Broger C., Cesura A.M.
Several aminotransferases with kynurenine aminotransferase (KAT) activity are able to convert L-kynurenine into kynurenic acid, a putative endogenous modulator of glutamatergic neurotransmission. In the rat, one of the described KAT isoforms has been found to correspond to glutamine transaminase K ... >> More
Several aminotransferases with kynurenine aminotransferase (KAT) activity are able to convert L-kynurenine into kynurenic acid, a putative endogenous modulator of glutamatergic neurotransmission. In the rat, one of the described KAT isoforms has been found to correspond to glutamine transaminase K. In addition, rat kidney alpha-aminoadipate aminotransferase (AadAT) also shows KAT activity. In this report, we describe the isolation of a cDNA clone encoding the soluble form of this aminotransferase isoenzyme from rat (KAT/AadAT). Degenerate oligonucleotides were designed from the amino acid sequences of rat kidney KAT/AadAT tryptic peptides for use as primers for reverse transcription-polymerase chain reaction of rat kidney RNA. The resulting polymerase chain reaction fragment was used to screen a rat kidney cDNA library and to isolate a cDNA clone encoding KAT/AadAT. Analysis of the combined DNA sequences indicated the presence of a single 1275-base pair open reading frame coding for a soluble protein of 425 amino acid residues. KAT/AadAT appears to be structurally homologous to aspartate aminotransferase in the pyridoxal 5'-phosphate binding domain. RNA blot analysis of rat tissues, including brain, revealed a single species of KAT/AadAT mRNA of approximately 2.1 kilobases. HEK-293 cells transfected with the KAT/AadAT cDNA exhibited both KAT and AadAT activities with enzymatic properties similar to those reported for the rat native protein. << Less
