Ascorbate protects tissues against damage caused by reactive oxygen species (ROS) produced through normal metabolism or generated from stress. The inositol route to AsA involves four enzymes: myo-inositol oxygenase, glucuronate reductase, gluconolactonase (GNL), and L-gulono-1,4-lactone oxidase (GulLO). Eighteen putative GNLs were identified in Arabidopsis, one of which, AtGNL, is interesting because it possesses a chloroplastic signal peptide. Knockouts on this gene had lower foliar AsA and stunted growth compared to controls. The functional gene restored the phenotype of the knockouts, and those plants had higher AsA content, enhanced photosynthetic capacity, and higher seed yield.

The invention relates to methods for enriching monomer content in a cycloalkane oxidation process mixed organic waste stream. In particular, the methods involve combining a biocatalyst with a mixed organic waste stream from a cycloalkane oxidation process, and enzymatically converting dimeric and/or oligomeric components of said waste stream into monomeric components. The methods may enrich the content of diacids, adipic acid, and/or other α,ω-difunctional C6 alkanes in the mixed organic waste stream. Additionally, the treated mixed organic waste streams may have improved burning efficiency.

This invention relates to genetically engineered strains of yeast and methods, for producing recombinant protein (e.g., collagen). Recombinant protein of the present invention is used to produce biofabricated leather or a material having leather-like properties containing recombinant or engineered collagen. The yeast strains are engineered to produce ascorbate and/or increased production of α ketoglutarate.

Provided are an esterase mutant and the use thereof. The esterase mutant obtained by means of rational design and several rounds of evolution screening with enzymes on the basis of an amino acid sequence as shown in SEQ ID NO: 1 is changed in terms of protein structure and function compared with a wild-type esterase; in practical use, the catalytic activity and/or stereoselectivity of the esterase mutant is greatly improved; and when a system contains some organic cosolvents, the esterase mutant still has relatively stable catalytic activity and/or stereoselectivity. In addition, the improvement of the catalytic activity and/or stereoselectivity of the esterase mutant reduces the use amount of the enzyme to a certain extent and reduces the difficulty of post-treatment, and therefore the esterase mutant is suitable for industrial production.
