Methods for identifying and producing polypeptides
First Claim
1. 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).

Abstract
In silico nucleic acid recombination methods, related integrated systems utilizing genetic operators and libraries made by in silico shuffling methods are provided. One disclosed method involves identifying and producing a polypeptide. The method may involve (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 thereby defining one or more recombinant polypeptides or recombinant nucleic acids; (c) selecting at least one of the recombinant polypeptides or recombinant nucleic acids; (d) recombining one or more oligonucleotides, at least one of which has a sequence matching some or all of that of the recombinant polypeptides or recombinant nucleic acids selected in (c); (e) selecting at least some of the recombined oligonucleotides produced in (d); and (f) producing a polypeptide encoded by the selected nucleic acid.
