摘要:
In recombinant microorganisms which were rendered capable of converting 2,5-diketo-D-gluconic acid (2,5-DKG) to 2-keto-L-gulonic acid (2-KLG) by transfer of genetic material, the secondary metabolites and metabolic pathways leading to the metabolic diversion of 2-KLG and 2,5-DKG were determined, and the diversion of 2-KLG to L-iodonic acid (IA) or of 2,5-DKG to 5-keto-D-gluconate (5-KDH) was blocked.
摘要:
Mutants of 2,5-diketo-D-gluconic acid reductase A, an enzyme used to produce 2-keto-L-gulonic acid, a precursor of ascorbic acid (vitamin C) are prepared by site-directed mutagenesis. These mutants have increased catalytic activity, increased expression levels, and/or enhanced temperature stability.

摘要:
The present invention relates to amino acid sequence variants of human DNase I that have increased DNA-hydrolytic activity. The invention provides nucleic acid sequences encoding such hyperactive variants, thereby enabling the production of these variants in quantities sufficient for clinical use. The invention also relates to pharmaceutical compositions and therapeutic uses of hyperactive variants of human DNase I.

The disclosure provides a crystal and crystal structure of the Hepatocyte Growth Factor Beta (HGF β) Chain, as well as use of the crystal structure in the design, identification, and selection of modulators of HGF or Met activity.
摘要:
This invention provides novel compounds which prevent or block a FVIIa mediated or associated process or event such as the catalytic conversion of FX to FXa, FVII to FVIIa or FIX to FIXa. In particular aspects, the compounds of the invention bind Factor VIIa (FVIIa), its zymogen Factor VII (FVII) and/or block the association of FVII or FVIIa with a peptide compound of the present invention. The invention also provides pharmaceutical compositions comprising the novel compounds as well as their use in diagnostic, therapeutic, and prophylactic methods.
摘要:
A potent serine protease inhibitor capable of inhibiting Factor VIIa, Factor XIa, plasma kallikrein, or plasmin is provided. The inhibitor is provided in a pharmaceutical composition for treatment of diseases where inhibition of Factor VIIa, Factor XIa, plasma kallikrein, or plasmin is indicated.
