The invention relates to a process for the preparation of colchicine 1 from colchicoside 2 which comprises enzymatic conversion of colchicoside 2 to 3-O-demethylcolchicine 3, wherein the enzyme used is a cellulase. According to another aspect of the invention, 3-O-demethylcolchicine 3 can be converted to colchicine 1 using an alkylating agent. The invention also relates to a process or enriching the colchicine 1 content of extracts from plants belonging to the Colchicaceae family containing colchicine 1, colchicoside 2 and 3-(9-demethyl colchicine 3, which comprises conversion by means of a colchicoside 2 cellulase to 3-O-demethylcolchicine 3, followed by conversion of 3-O-demethylcolchicine 3 to colchicine 1 using an alkylating agent.

The disclosure relates to compositions and methods for altering, e.g., enhancing, the expression of GCase proteins, whether in vitro and/or in vivo. Such compositions include delivery of an adeno-associated viral (AAV) particle. The compositions and methods of the present disclosure are useful in the treatment of subjects diagnosed with, or suspected of having Parkinson Disease or related condition resulting from a deficiency in the quantity and/or function of GBA gene product or associated with decreased expression or protein levels of GCase protein.

The present invention describes a intracellular produced lactase, which comprises less than 40 units arylsulfatase activity per NLU of lactase activity. The invention also provides a process comprising treating a substrate with an enzyme preparation, wherein the enzyme preparation is substantially free from arylsulfatase.

The present invention relates to a sterile-filtered liquid lactase preparation and to a method of sterile filtering a liquid lactase preparation.

A process for producing cellulolytic and/or hemicellulolytic enzymes with a strain of microorganism belonging to the family of filamentous fungi. The process includes growing the fungi in an aqueous culture medium, in the presence of at least one carbon-based growth substrate, in a stirred and aerated bioreactor. It also includes the production of enzymes, starting with the aqueous culture medium in the presence of at least one inductive carbon-based substrate and also inducing the production of hydrophobins. Further, at least a portion of the hydrophobins produced in step (b) are reintroduced into the growth step (a).

The present invention relates to xylanase variants of a parent xylanase having increased thermostability when compared to the parent xylanase. The present invention also relates to polynucleotides encoding the variants, nucleic acid constructs, vectors, and host cells comprising the polynucleotides, and method of producing the variants of the present invention.

The present disclosure provides methods for releasing intracellular proteins. The method allows isolation of the protein of interest from the cell without the requirement for mechanical disruption of the cells, without the need for isolation of the cells from the culture media, and without the need for removal of the cells from the culture media.

A method of modifying a glycosylation pattern of a polypeptide-of-interest in a plant or plant cell is provided. The method comprising expressing in a plant or plant cell transformed to express at least one glycosidase in a subcellular compartment, a nucleic acid sequence encoding the polypeptide-of-interest, such that the at least one glycosidase and the polypeptide-of-interest are co-localized to the subcellular compartment of the plant or plant cell, thereby modifying the glycosylation pattern of the polypeptide-of-interest in the plant or plant cell.

The purpose of this invention is to provide a method with which it is easy to perform screening for an agent that proliferates or an agent that minimizes the reduction in MCSP-positive basal epidermal stem cells. Provided is a screening method for a laminin 511 expression promoter, which takes the expression of laminin 511 as an indicator. Also provided is an agent for improving skin barrier function, elasticity, hydration and inflammation, said agent including at least one extract selected from among a group consisting of brown algae, red algae and green algae.

The present invention relates to a novel endoprotease, mutants thereof having binding but lacking or having reduced hydrolyzing activity, and use in methods of studying and isolating O-linked glycoproteins.
