Sequencing of the facB gene revealed that it encodes a protein that contains an N - terminal GAL4 - like Zn ( II ) 2Cys6 ( or C6 zinc ) binuclear cluster for DNA binding , leucine zipper - like heptad repeat motifs and central and C - terminal acidic alpha - helical regions , consistent with a function as a DNA - binding transcriptional activator .
