A 25-residue synthetic peptide corresponding to zinc finger 31 of the Xenopus protein Xfin adopts a compact, folded conformation in the presence of zinc. Complete 1H resonance assignments have been made. The peptide contains a helix, beginning as an alpha-helix and ending as a 3(10)-helix, that extends from residue 12 to 23. Several positively charged and polar residues located on this helix are likely to be involved in interactions with DNA. Residues 1-10 appear to adopt a hairpin-like structure.
