The resulting motif is a helix-turn-helix motif, in contrast to other zinc finger domains, which show anti-parallel sheet and helix conformation. Zinc binding occurs due to the presence of four cysteine residues positioned to bind the metal centre in a tetrahedral coordination geometry. Function of this domain is uncertain: it has been proposed that the zinc finger motif may be an essential part of the DNA binding domain [1].
