    摘要: The present disclosure relates to the production of highly efficient heterologous pathways in host cells by identifying favorable enzyme and/or promoter combinations. In particular the present disclosure provides methods for assembly and selection of multi-step xylose and arabinose/xylose utilization pathways from a library of fungal enzymes. The present disclosure further provides compositions containing favorable enzyme combinations, as well as recombinant yeast expressing such combinations, and methods of use for bioconversion of pentose sugars. Also provided are compositions and methods involving favorable expression patterns identified by utilization of combinations of promoters of varying strengths. Provided herein are methods for assembly and selection of multi-step xylose, arabinose/xylose, and cellobiose utilization pathways from a library of promoters of varying strengths. The present disclosure further provides compositions containing heterologous enzyme-coding polynucleotides under the control of favorable promoters, as well as recombinant yeast expressing such enzymes, and methods of their use for bioconversion of pentose and/or hexose sugars.

    摘要: The present invention relates to a method for tightly temporally controlling the biological activity of a protein of interest in a vertebrate, upon induction of the activity of a fusion protein comprising said protein of interest and an ERM polypeptide containing a mutated ligand binding domain of the human oestrogen receptor α, with a synthetic ligand that does not interfere with oestrogen signalling. In particular, the present invention concerns a method for generating tightly temporally-controlled targeted somatic mutations in a vertebrate, preferably a mouse, by inducing the activity of a fusion protein comprising a site-specific recombinase protein and an ERM polypeptide, with a synthetic ligand devoid of oestrogenic and anti-oestrogenic activities.

    摘要: The present invention provides a universal peptide-binding scaffold. This scaffold is used to bind a target. The target can be a peptide or peptides of interest (for example, peptides associated with a disease state) or can represent the entire proteome. The target can be either protein fragments prepared by enzymatic digestion of the entire proteome or N- or C-terminal short sequences exposed by chemical denaturation of the entire proteome (unfolded proteins). The universal peptide-binding scaffold can be tailored to specifically bind a target using the methods described herein.

    摘要: A new xylose reductase encoding gene from Neurspora crassa was heterologously expressed in E. coli as a His-tag fusion protein and subsequently purified in high yield. This xylose reductase was shown to have a high turnover rate and catalytic efficiency, high stability at room temperature, broad pH profile, and a preference of NADPH over NADH. This enzyme is utilized in production of xylitol and other sugar alcohols such as sorbitol and also in the metabolic enhancement of organisms used for fermentation of plant biomass into ethanol.
