Abstract excerpt
The azgA gene of Aspergillus nidulans encodes a hypoxanthine-adenine-guanine transporter. It has been cloned by a novel transposon methodology. The null phenotype of azgA was defined by a number of mutations, including a large deletion. In mycelia, the azgA gene is, like other genes of purine catabolism, induced by uric acid and repressed by ammonium. Its transcription depends on the pathway-specific UaY zinc...
