摘要:
Described herein are devices and methods for increasing the production of steviol glycosides, which have industrial and economic value. The steviol glycosides produced by the devices and methods disclosed herein do not require the ultra purification that is common in conventional or commercial methods and do not have a bitter aftertaste, making them better suited as flavor-enhancing additives to food, pharmaceutical, and nutritional supplement products.

The present disclosure relates to bifunctional chemical epigenetic modifiers, and methods of making, kits and using the bifunctional chemical epigenetic modifiers. The bifunctional chemical epigenetic modifiers can include a FK506 molecule or derivative thereof, a linker and a bifunctional ligand. The bifunctional ligand can be a histone deacetylase inhibitor.
摘要:
The present invention provides biocircuit systems, effector modules and compositions for cancer immunotherapy. Methods for inducing anti-cancer immune responses in a subject are also provided.
摘要:
A group of arabinose isomerases are disclosed that provide effective amounts of activity for use of arabinose in production of ethanol, when expressed in yeast cells expressing the other enzymes of an arabinose utilization pathway. The group of arabinose isomerases represents a clade of a phylogenetic tree, having a distinguishing conserved amino acid sequence motif. Other useful arabinose isomerases are also disclosed.
摘要:
This document describes biochemical pathways for producing pimeloyl-CoA using a polypeptide having the enzymatic activity of a hydroperoxide lyase to form non-3-enal and 9- oxononanoate from 9-hydroxyperoxyoctadec-10,12-dienoate. Non-3-enal and 9-oxononanoate can be enzymatically converted to pimeloyl-CoA or a salt thereof using one or more polypeptides having the activity of a dehydrogenase , a CoA ligase , an isomerase , a reductase , a thioesterase , a monooxygenase , a hydratase , and/or a thiolase . Pimeloyl-CoA can be enzymatically converted to pimelic acid, 7-aminoheptanoic acid, 7-hydroxyheptanoic acid, heptamethylenediamine, or 1,7-heptanediol, or corresponding salts thereof. This document also describes recombinant microorganisms producing pimeloyl-CoA, as well as pimelic acid, 7-aminoheptanoic acid, 7-hydroxyheptanoic acid, heptamethylenediamine, and 1,7-heptanediol, or corresponding salts thereof.
摘要:
The invention relates to method of treating or inhibiting progression of hemoglobinopathy in a subject in need thereof comprising inhibiting interaction between LRF-BTB and CHD protein-LBD.
摘要:
The present invention relates to a new class of peptides having antibacterial activity and presentin D-amino acids and their uses. It also relates to a new enzyme presenting a peptide epimeras activity in vitro and in vivo , thereby being useful for modifying peptides in order to change th amino acid configuration from L to D.
摘要:
The present invention provides methods for producing FKBP-type peptidyl-prolyl cis-trans isomerase (FkpA) polypeptides at very high levels of purity. Also provided are ultrapure FkpA and methods of using same, e.g., for use in immunoassays to show removal of FkpA from biologies produced in bacteria. In addition, the present invention provides methods of purifying polypeptides (e.g., multispecific antibodies) produced in bacteria overexpressing one or more chaperones. The methods include affinity chromatography, mixed-mode chromatography and hydrophobic interaction chromatography. In some aspects, the invention provides compositions of polypeptides (e.g., multispecific antibodies) that are essentially free of product-specific impurities.
