Patent ID: 7957912

Claim:
A method of identifying and producing a polypeptide, the method comprising: (a) receiving data identifying sequences of two or more parental polypeptides or parental nucleic acids that encode the polypeptides; (b) selecting one or more cross-over sites on the sequences based on structural or statistical information about the parental polypeptides or polypeptides encoded by the parental nucleic acids thereby defining one or more recombinant polypeptides or recombinant nucleic acids that result from cross-overs between the parental polypeptides or nucleic acids at the one or more cross-over sites; (c) selecting at least one of the recombinant polypeptides or recombinant nucleic acids; (d) identifying one or more oligonucleotides for recombination by choosing at least one portion of at least one of the recombinant polypeptides or recombinant nucleic acids selected in (c) which at least one portion identifies the one or more oligonucleotides for recombination; (e) recombining in vitro or in vivo the one or more oligonucleotides identified in (d), alone or in combination with other oligonucleotides to produce recombined oligonucleotides; (f) screening at least some of the recombined oligonucleotides produced in (e) to select a selected nucleic acid; and (g) producing a polypeptide encoded by the selected recombined nucleic acid selected in (f).
