| 20090275086 | ASSEMBLY OF LARGE NUCLEIC ACIDS - A method to assemble any desired nucleic acid molecule by combining cassettes in vitro to form assemblies which are further combined in vivo, or by assembling large numbers of DNA fragments by recombination in a yeast culture to obtain desired DNA molecules of substantial size is described. | 11-05-2009 |
| 20100035768 | METHODS FOR IN VITRO JOINING AND COMBINATORIAL ASSEMBLY OF NUCLEIC ACID MOLECULES - 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. | 02-11-2010 |
| 20100184187 | IN VITRO RECOMBINATION METHOD - 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. | 07-22-2010 |
| 20100291651 | RECOMBINANT HYDROGEN-PRODUCING CYANOBACTERIUM AND USES THEREOF - A recombinant cyanobacterium comprising an oxygen-tolerant, hydrogen-evolving hydrogenase, kit, and methods of use. | 11-18-2010 |
| 20100311126 | METHOD FOR IN VITRO RECOMBINATION - The present invention relates, e.g., to an 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 (a) chewing back the DNA molecules with an enzyme having an exonuclease activity, to yield single-stranded overhanging portions of each DNA molecule which contain a sufficient length of the region of sequence identity to hybridize specifically to each other; (b) specifically annealing the single-stranded overhangs; and (c) repairing single-stranded gaps in the annealed DNA molecules and sealing the nicks thus formed (ligating the nicked DNA molecules). The region of sequence identity generally comprises at least 20 non-palindromic nucleotides (nt), e.g., at least about 40 non-palindromic nt. In some embodiments of the invention, about 5% PEG is present during all steps of the reaction, and/or the repair reaction is achieved with Taq DNA polymerase and a compatible ligase, such as Taq DNA ligase. The method allows the joining of a 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. | 12-09-2010 |
| 20110053272 | METHODS FOR CLONING AND MANIPULATING GENOMES - Compositions and methods are disclosed herein for cloning a 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. | 03-03-2011 |
| 20110053273 | METHODS FOR CLONING AND MANIPULATING GENOMES - 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. | 03-03-2011 |
