Using Tris-acetate buffer rather than conventional phosphate buffer, it was possible to detect two distinct proteins capable of producing the neuroinhibitory brain metabolite kynurenic acid (KYNA) from L-kynurenine in human brain tissue. The two kynurenine aminotransferases (KATs), arbitrarily termed 'KAT I' and 'KAT II', could be physically separated by… CONTINUE READING
