  • Patent number: 10513724
    Abstract: The present disclosure relates to compositions and methods useful for the production of recombinant glycoproteins in filamentous fungal cells, such as Trichoderma cells, wherein at least 90% (mol %), preferably at least 95% of the total neutral N-glycans of said produced recombinant glycoprotein are mammalian-like N-glycans. More specifically, the invention provides a filamentous fungal cell comprising i. one or more mutations 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; iii. a recombinant polynucleotide for increasing ?1, 2 mannosidase activity;and, iv. a recombinant polynucleotide encoding said heterologous glycoprotein.
