Abstract excerpt
The two zinc fingers of the yeast transcription factor Adr1p recognize the 6 bp sequence TTG GAG site in which the first finger, a His-X3-His finger, recognizes the G-rich triplet (GAG) and the second zinc finger, a His-X4-His finger, recognizes the T-rich sequence (TTG). Mutations were introduced into the alpha-helical region of the second finger and the resultant mutant proteins were analyzed for DNA binding...
