  • Patent number: 11466248
    Abstract: The present invention provides Streptomyces coelicolor strain A3(2)_M22-2C43 obtained by inducing a point mutation in the base sequence of the DagB gene in a wild-type Streptomyces coelicolor strain A3(2) by UV radiation. Since the Streptomyces coelicolor strain A3(2)_M22-2C43 according to the present invention expresses a DagB mutant enzyme expressing little or no DagB beta-agarase or exhibiting little or no beta-agarase activity, there is no need for separate isolation and purification of DagA enzymes from culture fluid, and the culture fluid of the Streptomyces coelicolor strain A3(2)_M22-2C43 or supernatant thereof may be used to produce, from agar or agarose, neoagarose oligosaccharides with a higher content of neoagarotetraose or neoagarohexaose than that of neoagarobiose.

  • Patent number: 11447824
    Abstract: Provided are compositions and methods for detecting a target DNA (double stranded or single stranded) in a sample. In some embodiments, a subject method includes: (a) contacting the sample with: (i) a type V CRISPR/Cas effector protein (e.g., a Cas12 protein such as Cas12a, Cas12b, Cas12c, Cas12d, Cas12e); (ii) a guide RNA (comprising a region that binds to the type V CRISPR/Cas effector protein, and a guide sequence that hybridizes with the target DNA); and (iii) a detector DNA that is single stranded (i.e., a “single stranded detector DNA”) and does not hybridize with the guide sequence of the guide RNA; and (b) measuring a detectable signal produced by cleavage (by the type V CRISPR/Cas effector protein) of the single stranded detector DNA. Also provided are compositions and methods for cleaving single stranded DNAs (e.g., non-target ssDNAs), e.g., inside of a cell.

  • Patent number: 11427837
    Abstract: The present disclosure provides methods and compositions for enhanced editing of genomic DNA. For example, in some embodiments, a subject method is a method of editing genomic DNA of a eukaryotic cell and the method includes introducing into a eukaryotic cell a composition comprising: (a) a linearized non-homologous DNA composition and (b) a genome targeting composition (which includes a genome editing endonuclease, or a nucleic acid encoding the genome editing endonuclease). In some cases in which the genome editing endonuclease is a CRISPR/Cas endonuclease, the genome targeting composition can also include a corresponding CRISPR/Cas guide RNA.
