English: Comparison through alignment of the structure of the computationally designed protein sequence FSD-1 (blue, PDB id: 1FSV) with the structure of the zinc finger in residues 33-60 of the structure of protein Zif268 used as a template (red, PDB id: 1ZAA). This was the first full sequence de novo design of a protein. Reference: Dahiyat, Bassil I., and Stephen L. Mayo. "De novo protein design: fully automated sequence selection."
