摘要:
This disclosure provides methods and compositions for the promotion of enzymatic activity of Target Enzymes, including but not limited to oligosaccharide/polysaccharide enzymes, protein enzymes, polynucleotide enzymes. The methods involve use of a non-naturally occurring polysaccharide (including but not limited HES) for promoting the enzymatic activity of an enzyme in liquid milieu, wherein the concentration of the polysaccharide in the composition comprising the Target Enzyme is from about 0.01 % to about 55% w/v.
摘要:
Methods for manipulating carbohydrate processing pathways in cells of interest are provided. Methods are directed at manipulating multiple pathways involved with the sialylation reaction by using recombinant DNA technology and substrate feeding approaches to enable the production of sialylated glycoproteins in cells of interest. These carbohydrate engineering efforts encompass the implementation of new carbohydrate bioassays, the examination of a selection of insect cell lines and the use of bioinformatics to identify gene sequences for critical processing enzymes. The compositions comprise cells of interest producing sialylated glycoproteins. The methods and compositions are useful for heterologous expression of glycoproteins.
摘要:
Method for treating a hydrophobically-modified textile with an aqueous solution of a nuclease enzyme, preferably a deoxyribonuclease or ribonuclease enzyme, rinsing and drying the textile. Use of the finishing step for improved cleaning with an aqueous solution of a nuclease enzyme, preferably a deoxyribonuclease or ribonuclease enzyme
摘要:
Embodiments herein include variants of β-hexosaminidase that are useful for hydrolyzing GM2 ganglioside, polynucleotides encoding the same, and related methods. In various embodiments, a variant β-hexosaminidase subunit is included wherein the variant β-hexosaminidase subunit forms a homodimer under physiological conditions and wherein the variant β- hexosaminidase subunit associates with GM2 activator protein to hydrolyze GM2 ganglioside. In some embodiments, an isolated or recombinant polynucleotide encoding such a variant β-hexosaminidase subunit is included. In some embodiments, a method of treating a subject exhibiting an abnormal cellular accumulation of GM2 ganglioside is included wherein the method includes administering a composition including a protein variant of β-hexosaminidase or a polynucleotide encoding the same. Other embodiments are included herein.
摘要:
The present invention relates generally to phosphorylated glycoproteins and glycopeptides, methods of chemoenzymatic synthesis of phosphorylated glycoproteins or glycopeptides, compositions comprising such phosphorylated glycoproteins or glycopeptides, therap eutic methods utilizing such phosphorylated glycoproteins or glycopeptides, and to the use of such phosphorylated glycoproteins or glycopeptides in the manufacture of medicaments.
摘要:
In alternative embodiments, the invention provides compositions and methods for treating various disorders and conditions in mammals, including chronic disorders in which there is a presence of an abnormal microbiota or an abnormal distribution of microflora in the gastrointestinal tract. In alternative embodiments, the invention provides liquid preparations or formulations derived from a human fecal material (e.g., a stool) processed, e.g., filtered and/or centrifuged, such that all bacteria, fungal spores and viruses are removed, but retaining the native biologically active molecules from the fecal material and bacteriophages. In alternative embodiments, the invention provides a "rough-", "incomplete-" or medium- filtered microbiota which still comprises native physiological components or nutritive agents for the bacteria, e.g., retains native biologically and nutritionally active components. In alternative embodiments, the invention provides a highly filtered or substantially purified microbiota in combination with, or having added back, a liquid preparation or formulation of the invention. In alternative embodiments, the invention provides compositions or formulations where the bacteria, or microbiota, component has been cultured, or cultured under anaerobic conditions, or harvested, stored and/or cultured under anaerobic conditions. In alternative embodiments, the invention provides various additives, compositions and donor restrictions for treating these disorders and conditions.
摘要:
Plant-expressed human recombinant DNase proteins, nucleic acid constructs for expression of the human recombinant DNase I in plant cells, cells expressing the nucleic acid construct and therapeutic uses thereof are disclosed. Particularly, compositions and methods for treating pulmonary and/or respiratory conditions by inhalation of the plant- expressed human recombinant DNase I are provided.
