  • Patent number: 9206433
    Abstract: Methods and kits for joining two or more polynucleotides to form a product polynucleotide are provided. A mixture contains a first polynucleotide comprising a selectable marker. The mixture further contains a second polynucleotide comprising a first typeIIs recognition sequence and a second typeIIs recognition sequence. The second polynucleotide is other than the first polynucleotide. The mixture further contains a first typeIIs restriction endonuclease that cleaves the first typeIIs recognition sequence to produce a first end, a second typeIIs restriction endonuclease that cleaves the second typeIIs recognition sequence to produce a second end, and a DNA ligase. The first end is not compatible with the second end. The combined actions of the enzymes in the mixture join the first polynucleotide to the second polynucleotide forming a product polynucleotide, which is obtained by transforming the mixture into a host cell.

    Abstract: Methods, computer systems, and computer program products for biopolymer engineering. A variant set for a biopolymer of interest is constructed by identifying, using a plurality of rules, a plurality of positions in the biopolymer of interest and, for each respective position in the plurality of positions, substitutions for the respective position. The plurality of positions, and the substitutions for each respective position in the plurality of positions collectively defined a biopolymer sequence space. A variant set comprising a plurality of variants of the biopolymer of interest is selected. A property of all or a portion of the variants in the variant set is measured. A sequence-actively relationship is modeled between (i) one or more substitutions at one or more positions of the biopolymer of interest represented by the variant set and (ii) the property measured for all or the portion of the variants in the variant set.

  • Publication number: 20130183664
    Abstract: Methods for determining a property that affects expression of polynucleotides are provided. A plurality of polynucleotides each encoding a polypeptide sequence is constructed. A frequency that a sequence element is used in a first polynucleotide is different than in a second polynucleotide. Each polynucleotide is expressed in an expression system to obtain an expression property value thereby constructing a dataset that contains, for each respective polynucleotide, sequence element occurrence in the respective polynucleotide and the measured expression property value of the respective polynucleotide. A model is computed that describes variation in the measured expression property values as a function of a plurality of variables and weights.

  • Patent number: 8126653
    Abstract: A method of determining a property that affects expression of polynucleotides in an expression system. A plurality of polynucleotides, each encoding a polypeptide sequence, is constructed. An amino acid is encoded a plurality of times in both a first and second polynucleotide in the plurality. The amino acid is encodable by a plurality of synonymous codons including a first codon. The first codon is in the first polynucleotide at a first frequency relative to other synonymous codons, and is in the second polynucleotide at a second frequency relative to other synonymous codons. The first and second frequencies are different. Each polynucleotide is individually expressed in the expression system to measure an expression property value of the polynucleotides, thereby determining a property that affects expression of polynucleotides. The property is an effect that a frequency of use of one or more codons has on expression of polynucleotides in the expression system.
