Patent number: 8129115Abstract: A nucleotide chain to be modified, a nucleotide having a particular base that is different from bases constituting the nucleotide chain, an enzyme catalyzing addition of the nucleotide to the 3?-terminus of the nucleotide chain, a degrading enzyme acting specifically on the nucleotide, and a desired modifier for modifying the nucleotide chain are allowed to coexist in a buffer solution as a mixture solution such that: the nucleotide is added to the 3?-terminus of the nucleotide chain; the sequence of the added nucleotide is degraded to form, at the 3?-terminus of the nucleotide chain, a functional group capable of binding to the modifier; and the 3?-terminus of the nucleotide chain having the functional group thus formed is directly modified with the modifier. The reactions at three stages continuously proceed in the mixture solution. As a result, simplified procedures and reduced reaction time can be achieved.Type: GrantFiled: June 4, 2007Date of Patent: March 6, 2012Assignee: Panasonic CorporationInventor: Shigeki Joko

Patent number: 8129116Abstract: A method for replicating and amplifying a target nucleic acid sequence is described. A method of the invention involves the formation of a recombination intermediate without the prior denaturing of a nucleic acid duplex through the use of a recombination factor. The recombination intermediate is treated with a high fidelity polymerase to permit the replication and amplification of the target nucleic acid sequence. In preferred embodiments, the polymerase comprises a polymerase holoenzyme. In further preferred embodiments, the recombination factor is bacteriophage T4 UvsX protein or homologs from other species, and the polymerase holoenzyme comprises a polymerase enzyme, a clamp protein and a clamp loader protein, derived from viral, bacteriophage, prokaryotic, archaebacterial, or eukaryotic systems.Type: GrantFiled: May 24, 2010Date of Patent: March 6, 2012Assignee: The Penn State Research FoundationInventors: Stephen J. Benkovic, Frank Salinas

Patent number: 8129119Abstract: The present invention provides an improved system for linking nucleic acids to one another. In particular, the present invention provides techniques for producing DNA product molecules that may be easily and directly ligated to recipient molecules. The product molecules need not be cleaved with restriction enzymes in order to undergo such ligation. In preferred embodiments of the invention, the DNA product molecules are produced through iterative DNA synthesis reactions, so that the product molecules are amplified products. The invention further provides methods for directed ligation of product molecules (i.e., for selective ligation of certain molecules within a collection of molecules), and also for methods of exon shuffling, in which multiple different product molecules are produced in a single ligation reaction. Preferred embodiments of the invention involve ligation of product molecules encoding functional protein domains, particularly domains naturally found in conserved gene families.Type: GrantFiled: May 4, 2006Date of Patent: March 6, 2012Assignee: Modular Genetics, Inc.Inventors: Kevin Jarrell, Brian Turczyk
