Drysdale MR, et al. (1993) The Aspergillus niger carbon catabolite repressor encoding gene, creA. Gene 130(2):241-5
Abstract: In order to undertake a comparative analysis of carbon catabolite repression in two Aspergillus species, the creA gene has been isolated from A. niger by cross hybridization, using the cloned A. nidulans gene. The A. niger gene has been shown to be functional in A. nidulans by heterologous complementation of the creA204 mutation of A. nidulans. Overall, the genes show 90% sequence similarity (82% identity) at the amino acid (aa) level. There were some striking similarities between the aa sequences encoded by the two fungal creA genes and two genes involved in carbon catabolite repression in Saccharomyces cerevisiae. The zinc-finger regions showed 96% similarity (84% identity) with the zinc-finger region of the MIG1 gene of S. cerevisiae. The CREA protein contains a stretch of 42 aa that is identical in A. niger and A. nidulans, and these show 81% similarity (33% identity) with a region of the S. cerevisiae RGR1 gene.
