    The structure of a CCHHC zinc-binding domain from neural zinc finger factor-1 (NZF-1) has been determined in solution though the use of NMR methods. This domain is a member of a family of domains that have the Cys-X(4)-Cys-X(4)-His-X(7)-His-X(5)-Cys consensus sequence. The structure determination reveals a novel fold based around a zinc(II) ion coordinated to three Cys residues and the second of the two conserved His residues. The other His residue is stacked between the metal-coordinated His residue and a relatively conserved aromatic residue. Analysis of His to Gln sequence variants reveals that both His residues are required for the formation of a well-defined structure, but neither is required for high-affinity metal binding at a tetrahedral site. The structure suggests that a two-domain protein fragment and a double-stranded DNA binding site may interact with a common two-fold axis relating the two domains and the two half-sites of the DNA-inverted repeat.
