  • Patent number: 11542529
    Abstract: The present invention relates, e.g., to in vitro method, using isolated protein reagents, for joining two double stranded (ds) DNA molecules of interest, wherein the distal region of the first DNA molecule and the proximal region of the second DNA molecule share a region of sequence identity, comprising contacting the two DNA molecules in a reaction mixture with (a) a non-processive 5? exonuclease; (b) a single stranded DNA binding protein (SSB) which accelerates nucleic acid annealing; (c) a non strand-displacing DNA polymerase; and (d) a ligase, under conditions effective to join the two DNA molecules to form an intact double stranded DNA molecule, in which a single copy of the region of sequence identity is retained. The method allows the joining of a number of DNA fragments, in a predetermined order and orientation, without the use of restriction enzymes.

  • Patent number: 11408020
    Abstract: The present invention relates to methods of joining two or more double-stranded (ds) or single-stranded (ss) DNA molecules of interest in vitro, wherein the distal region of the first DNA molecule and the proximal region of the second DNA molecule of each pair share a region of sequence identity. The method allows the joining of a large number of DNA fragments, in a predetermined order and orientation, without the use of restriction enzymes. It can be used, e.g., to join synthetically produced sub-fragments of a gene or genome of interest. Kits for performing the method are also disclosed. The methods of joining DNA molecules may be used to generate combinatorial libraries useful to generate, for example, optimal protein expression through codon optimization, gene optimization, and pathway optimization.

  • Patent number: 11203761
    Abstract: The present disclosure provides engineered Vibrio sp. organisms. The organisms can be engineered to have an altered Chromosome II so that the altered Chromosome II can be used in Vibrio sp. and other organisms for the cloning or amplification of nucleic acid molecules and for the expression and production of proteins and peptides in a Vibrio sp. organism. One or more genetic elements have been deleted from Chromosome II and/or relocated from Chromosome II to Chromosome I. The engineered Vibrio sp. organisms of the invention can also have signal sequences fused to proteins or peptides to be secreted from the cell. In some embodiments the engineered Vibrio sp. organisms can have sequences that enable them to retain viability after incubation at low temperatures.

  • Patent number: 11060137
    Abstract: The invention provides compositions and methods for assembling a DNA molecule having a desired sequence. The methods involve contacting a DNA polymerase, dNTPs, and a plurality of pairs of oligonucleotides. The oligonucleotides of a pair have a portion of the desired sequence, and an internal sequence that overlaps and is complementary to an internal sequence of the other oligonucleotide of the pair, and, when arranged in order, they have at least a portion of the desired sequence. The oligonucleotides also have a 3? or a 5? primer binding sequence having a binding site for a primer. The oligonucleotides that correspond to the end oligonucleotides of the desired sequence also have a universal 3? flanking sequence and a universal 5? flanking sequence, respectively.

  • Patent number: 11027282
    Abstract: The present invention provides a system for receiving biological sequence information and activating the synthesis of a biological entity. The system has a receiving unit for receiving a signal encoding biological sequence information transmitted from a transmitting unit. The transmitting unit can be present at a remote location from the receiving unit. The system also has an assembly unit connected to the receiving unit, and the assembly unit assembles the biological entity according to the biological sequence information. Thus, according to the present invention biological sequence information can be digitally transmitted to a remote location and the information converted into a biological entity, for example a protein useful as a vaccine, immediately upon being received by the receiving unit and without further human intervention after preparing the system for receipt of the information.

  • Patent number: 10975378
    Abstract: Compositions and methods are disclosed herein for cloning a synthetic or a semi-synthetic donor genome in a heterologous host cell. In one embodiment, the donor genome can be further modified within a host cell. Modified or unmodified genomes can be further isolated from the host cell and transferred to a recipient cell. Methods disclosed herein can be used to alter donor genomes from intractable donor cells in more tractable host cells.

  • Patent number: 10968496
    Abstract: The invention provides engineered Vibrio sp. organisms that comprise a genetic modification to either or both of the lpxL and/or lpxM genes. The organisms score substantially lower in an in vitro endotoxin assay versus the unmodified or wild type organism. The organisms preserve substantially the growth rate of the corresponding unmodified organisms. The organisms can also have an exogenous nucleic acid cloned in the organism, or an exogenous nucleic acid encoding a protein, polypeptide, or peptide expressed by the organism, and optionally secreted from the organism.

  • Patent number: 10818378
    Abstract: Methods and apparatus are disclosed herein for encoding human readable text conveying a non-genetic message into nucleic acid sequences with a substantially reduced probability of biological impact and decoding such text from nucleic acid sequences. In one embodiment, each symbol of a symbol set of human readable symbols uniquely maps to a respective codon identifier. Mapping may ensure that each symbol will not map to a codon identifier that generates an amino acid residue which has a single-letter abbreviation that is the equivalent to the respective symbol. Synthetic nucleic acid sequences comprising such human readable text, and recombinant or synthetic cells comprising such sequences are provided, as well as methods of identifying cells, organisms, or samples containing such sequences.

  • Patent number: 10704041
    Abstract: The present invention provides materials and methods useful for error correction of nucleic acid molecules. In one embodiment of the invention, a first plurality of double-stranded nucleic acid molecules having a nucleotide mismatch are fragmented by exposure to a molecule having unidirectional mismatch endonuclease activity. The nucleic acid molecules are cut at the mismatch site or near the mismatch site, leaving a double-stranded nucleic acid molecule having a mismatch at the end or near end of the molecule. The nucleic acid molecule is then exposed to a molecule having unidirectional exonuclease activity to remove the mismatched nucleotide. The missing nucleotides can then be filled in by the action of, e.g., a molecule having DNA polymerase activity. The result is double-stranded nucleic acid molecules with a decreased frequency of nucleotide mismatches.
