  • Patent number: 10450593
    Abstract: This disclosure describes enzymes from the type II (a discrete set of enzymes) fatty acid synthesis (“FAS”) pathway that can be used in combination with thiolases to operate a functional reversal of the ?-oxidation cycle. A combination of thiolases with one or more of 3-oxoacyl-[acyl-carrier-protein] reductase (FabG, others), 3-hydroxyacyl-[acp] dehydratase (FabA, FabZ, others), and enoyl-[acyl-carrier-protein] reductase (FabI, FabK, FabL, FabV, others) yields a functional reversal of the ?-oxidation cycle. If only one or two enzymes are used, the remaining enzymes will be traditional beta oxidation enzymes. Once this cycle is coupled with the appropriate priming and termination pathways, the production of carboxylic acids, alcohols, hydrocarbons, amines and their ?-, ?-, and ?-functionalized derivatives from renewable carbon sources can be achieved.

  • Patent number: 10385332
    Abstract: The present invention is based, at least in part, on the development of a mating-based yeast two-hybrid screen that allows simultaneous screening for mutations that disrupt yeast two-hybrid interactions between a protein and multiple interacting partners. By coupling PCR mutagenesis and homologous recombination/gapped plasmid repair with a mating-based assay, the present invention allows screening for unique mutations that disrupt interaction with one partner, but not others. It also allows identification of specific mutations that may lie at protein-protein interfaces common to two or more partners, without employing multiple rounds of screening. In addition to screening against multiple interacting partners, the present invention removes the need for a two-step selection because truncations, frameshifts, or any mutations that affect folding are eliminated as disruptions that affect all protein partners.

  • Patent number: 10385397
    Abstract: Methods are provided for determining whether a subject has a graft tolerant phenotype. In practicing the subject methods, the expression level of one or more gene in a sample from the subject, e.g., a blood sample, is assayed to obtain a gene expression result, where the gene expression result includes a result for a biomarker of graft tolerance. The obtained gene expression result is then employed to determine whether the subject has a graft tolerant phenotype. Also provided are compositions, systems and kits that find use in practicing the subject methods. The methods and compositions find use in a variety of applications, including the determination of an immunosuppressive therapy regimen.

  • Patent number: 10365269
    Abstract: This disclosure describes a cell genetically modified to detect ribosome inhibition in the cell and methods involving such a cell. Generally, the genetically-modified cell includes an aminoglycoside-sensitive orthogonal 16S rRNA (O-16S) coding region bearing a mutated anti-Shine-Dalgarno (O-ASD) sequence, a repressor/operator system, and a polynucleotide encoding a detectable reporter under transcriptional control of the repressor/operator system. The repressor/operator system includes a coding region that encodes a transcriptional regulator and having an orthogonal SD (O-SD) sequence complementary to the 16S rRNA O-ASD sequence. The operator sequence, which is repressable by the transcriptional regulator, is operably linked to the polynucleotide encoding a detectable reporter.
