  • Publication number: 20250051821
    Abstract: Disclosed are compositions and methods involving proteases specific for mannose-modified proteins. The compositions and methods are particularly useful for making linker-specific cleavages in proteins produced by yeast and fungal cells. One use of the compositions and methods is for agglomerating yeast and yeast components in fermentation products. Another use of the composition is for producing a fraction of protein with reduced carbohydrate content.
