摘要
Expression of the Aspergillus nidulans brlA gene induces a developmental pathway leading to the production of asexual spores. We have introduced mutations into brlA that are expected to disrupt either or both Cys2-His2 Zn(II) coordination sites postulated to exist in the BrlA polypeptide. The resultant brlA alleles fail to induce either the asexual reproductive pathway or the expression of development-specific genes. These data support the hypothesis that brlA encodes a nucleic acid-binding protein whose activity requires each of two zinc fingers.
