Abstract: Cysteine engineered monospecific and bispecific EGFR and/or c-Met FN3 domain containing molecules comprising one or more free cysteine amino acids are prepared by mutagenizing a nucleic acid sequence of a parent molecule and replacing one or more amino acid residues by cysteine to encode the cysteine engineered FN3 domain containing monospecific or bispecific molecules; expressing the cysteine engineered FN3 domain containing molecules; and recovering the cysteine engineered FN3 domain containing molecule. Isolated cysteine engineered monospecific or bispecific FN3 domain containing molecules may be covalently attached to a detection label or a drug moiety and used therapeutically.

Abstract: Focal and segmental glomerulosclerosis (FSGS) is a kidney disorder of unknown etiology and up to 20% of patients on dialysis have this diagnosis. A large family with hereditary FSGS carries a missense mutation in the TRPC6 gene on chromosome 11q, encoding the ion channel protein Transient Receptor Potential Cation Channel 6. The missense mutation is a P112Q substitution, which occurs in a highly conserved region of the protein, enhances TRPC6-mediated calcium signals in response to agonists such as angiotensin II, and alters the intracellular distribution of TRPC6 protein. Previous work has emphasized the importance of cytoskeletal and structural proteins in proteinuric kidney diseases. Our findings suggest a novel mechanism for glomerular disease pathogenesis.

Abstract: A process for producing ethanol includes steps of pre-treatment of the lignocellulosic vegetable raw material, including the steps consisting in destructuring the lignocellulosic vegetable raw material, then in separating, on the one hand, the cellulose (C6) capable of then being hydrolysed (and fermented for the production of ethanol) and, on the other hand, the hemicelluloses capable of then being hydrolysed and the lignins. The hydrolysis of the cellulose and of the hemicelluloses is then carried out in a sequenced manner according to the following steps consisting in: i) beginning the enzymatic hydrolysis of the cellulose by at least one enzyme for a first period with a view to obtaining an intermediate hydrolysate; ii) adding hemicelluloses to the intermediate hydrolysate; iii) continuing the enzymatic hydrolysis of the mixture until a final hydrolysate is obtained at the end of a total period of enzymatic hydrolysis.

Abstract: The present invention provides an EndoS mutant enzyme having an amino acid sequence of EndoS D233Q and further having a particular additional mutation and exhibiting a reduced hydrolysis activity, in comparison with the activity of EndoS D233Q, to an N-linked sugar chain (N297-linked sugar chain) linked to Asn at position 297 in IgG and a gene encoding the same.
Abstract: The present disclosure discloses a thermophilic L-asparaginase mutant and screening and fermentation methods thereof, and belongs to the field of gene engineering, enzyme engineering and fermentation engineering. In Bacillus subtilis 168, a Pyrococcus yayanosii CH1-derived L-asparaginase encoding gene is used as a template, and a mutation library is constructed by an error-prone PCR (epPCR) technology. A mutant strain with improved specific enzyme activity is screened through a high-flux screening method of synchronous cell disruption and enzyme activity measurement. Mutated residues included in a positive mutant are analyzed to construct a composite mutant strain S17G/A90S/R156S/K272A with improved specific enzyme activity and specific enzyme activity of 3108 U/mg. An expression quantity of the composite mutant strain in the Bacillus subtilis 168 is increased through measures of a strong promoter P43 and RBS optimization.

Abstract: The purpose of the present invention is to provide: a liver-type fatty acid-binding protein standard by which, in a measurement using a specifically binding substance, the range of variation of a measured value caused by a liver-type fatty acid-binding protein can be narrowed; a method of evaluating the standard; a method of drawing a calibration curve of a liver-type fatty acid-binding protein; and a method of quantifying the protein. A liver-type fatty acid-binding protein standard in which a coefficient of change in oxidation, said coefficient being represented by the ratio of a measured value obtained by using a liver-type fatty acid-binding protein standard having been subjected to an oxidation treatment with 10 mM of an oxidant for 1 hour at 25° C. to a measured value obtained by using the liver-type fatty acid-binding protein standard not subjected to the oxidation treatment, is set to 1.
