What is the definition of zinc finger motif?

Motifs in DNA- and RNA-binding proteins whose
amino acids are folded into a single structural
unit around a zinc atom. In the classic zinc
finger, one zinc atom is bound to two cysteines
and two histidines. In between the cysteines and
histidines are 12 residues which form a DNA
binding fingertip. By variations in the
composition of the sequences in the fingertip and
the number and spacing of tandem repeats of the
motif, zinc fingers can form a large number of
different sequence specific binding sites.
