The present invention is related to variants of fungal serine protease enzyme, which have serine protease activity of Malbranchea protease. Also disclosed are isolated nucleic acid molecules, comprising polynucleotide sequences which encode variants of fungal serine protease enzyme, nucleic acid sequences encoding said protease variants, a host cell and a process of producing polypeptides having serine protease activity. Said protease variants are useful as enzyme preparations applicable in detergent compositions and for treating fibers, wool, hair, leather, or silk, for treating food or feed, or for any applications involving modification, degradation or removal of proteinaceous material.

The instant disclosure is generally related to microbial fermentation, grain processing and ethanol production. Certain embodiments of the disclosure are therefore related to starch-containing materials and the microbial fermentation of such starch-containing materials for the production ethanol. More particularly, certain embodiments are related to novel protease mixtures for use in processing such starch-containing materials in starch to ethanol fermentation processes described herein.

The present disclosure relates to serine proteases cloned from Bacillus spp., and variants thereof. Compositions containing the serine proteases are suitable for use in cleaning fabrics and hard surfaces, as well as in a variety of industrial applications.

The invention relates to RNAi agents, e.g., double-stranded RNAi agents, targeting the PCSK9 gene, and methods of using such RNAi agents to inhibit expression of PCSK9 and methods of treating subjects having a lipid disorder, such as a hyperlipidemia.

The present invention relates to protease variants and methods for obtaining protease variants. The present invention also relates to polynucleotides encoding the variants; nucleic acid constructs, vectors, and host cells comprising the polynucleotides; and methods of using the variants.

This disclosure relates to novel SARS-CoV-2 targeting sequences. Novel SARS-CoV-2 targeting oligonucleotides for the treatment of SARS-CoV-2 infection are also provided.

The present invention relates to a method for obtaining chitin and/or chitosan from insect cuticles. More particularly, the method according to the present invention comprises a first enzymatic hydrolysis of insect cuticles using at least one endopeptidase, separation from the hydrolysis medium of the hydrolyzed cuticles resulting from the first enzymatic hydrolysis, and a second enzymatic hydrolysis of the hydrolyzed cuticles using at least one endopeptidase, excluding exopeptidase.

Methods for detection, diagnosis, prognosis, theragnosis, and targeted therapy of a PRSS21-overexpressing condition (e.g., cancer), in particular, PRSS21-overexpressing acute myeloid leukemia of the AMKL subtype.

The present disclosure provides methods of preparing a fixed biological sample for use in an assay, wherein the method includes treatment of the sample with a low temperature active protease, optionally, in combination with an un-fixing reagent. The disclosure also provides assay methods, include partition-based methods, for fixed biological sample that use the low temperature protease treatment in combination with an un-fixing reagent. Kits comprising protease compositions, un-fixing agent compositions, and other assay reagents for use in the methods are also provided.

Disclosed herein are embodiments of a compound useful for treating or preventing SARS-Cov-2 infections. Also disclosed is a method for administering the compound to a subject, particularly a human subject, to treat or prevent a SARS-CoV-2 infection in the subject. The compound may comprise an oligomer comprising a nucleic acid base sequence that is antisense to a gene, pre-mRNA or mRNA in the subject, such as a gene, pre-mRNA or mRNA of transmembrane serine protease 2 (TMPRSS2). The compound also may comprise a peptide sequence. In some embodiments, the compound is a peptide-conjugated phosphorodiamidate morpholino oligomer (PPMO).
