Described herein are mammalian cells engineered to express and secrete an ARSB protein and optionally a sialytransferase protein, as well as compositions, implantable devices and device preparations comprising the engineered cells, and methods of making and using the same for treating MPS VI disease.

Preparations including recombinant FSH (rFSH).

Provided herein are host cells capable of producing hybrid oligosaccharides and polysaccharides, wherein said hybrid oligosaccharides and polysaccharides do not comprise a hexose at the reducing end of their first repeat unit. Also provided herein are hybrid oligosaccharides or polysaccharides and bioconjugates which can be produced by the host cells described herein, wherein said bioconjugates comprise a carrier protein linked to a hybrid oligosaccharide or polysaccharide that does not comprise a hexose at the reducing end of its first repeat unit.

Disclosed are methods, systems, components, and compositions for cell-free synthesis of glycosylated carrier proteins. The glycosylated carrier proteins may be utilized in vaccines, including anti-bacterial vaccines. The glycosylated carrier proteins may include a bacterial polysaccharide conjugated to a carrier, which may be utilized to generate an immune response in an immunized host against the polysaccharide conjugated to the carrier. The glycosylated carrier proteins may be synthesized in cell-free glycoprotein synthesis (CFGpS) systems using prokaryote cell lysates that are enriched in components for glycoprotein synthesis such as oligosaccharyltransferases (OSTs) and lipid-linked oligosaccharides (LLOs) including OSTs and LLOs associated with synthesis of bacterial O antigens.

The present disclosure relates to compositions and methods useful for the production of heterologous proteins with increased N-glycosylation site occupancy in filamentous fungal cells, such as Trichoderma cells. More specifically, the invention provides a filamentous fungal cell comprising i. one or more mutation that reduces or eliminates one or more endogenous protease activity compared to a parental filamentous fungal cell which does not have said mutation(s), ii. a polynucleotide encoding a heterologous catalytic subunit of oligosaccharyl transferase, and iii. a polynucleotide encoding a heterologous glycoprotein, wherein said catalytic subunit of oligosaccharyl transferase is selected from Leishmania oligosaccharyl transferase catalytic subunits.

Described herein are novel methods of inserting nucleic acid sequences into host cells. Also described herein are genetically stable host cells comprising inserted nucleic acid sequences and methods of using such host cells in the generation of proteins.

Methods for recombinant production of steviol glycoside and compositions containing steviol glycosides are provided by this invention.

Provided herein are host cells capable of producing hybrid oligosaccharides and polysaccharides, wherein said hybrid oligosaccharides and polysaccharides do not comprise a hexose at the reducing end of their first repeat unit. Also provided herein are hybrid oligosaccharides or polysaccharides and bioconjugates which can be produced by the host cells described herein, wherein said bioconjugates comprise a carrier protein linked to a hybrid oligosaccharide or polysaccharide that does not comprise a hexose at the reducing end of its first repeat unit.

This invention provides purified and recombinantly-produced bacterial lipoprotein signal peptidase (Lsp) enzymes and in vitro assays for monitoring Lsp catalytic activities. Also provided in the invention are screening methods for identifying novel antibiotic agents and their therapeutic applications for treating bacterial infections. Further provided in the invention are specific Lsp inhibitory compounds which can be used as bactericidal agents in treating diseases caused by bacterial infections.

The present invention relates to methods of immunomodulation and treating patients having solid tumors with antibodies that specifically bind CD38.
