A novel serine protease from strawberry (Fragaria ananassa): Purification and biochemical characterization

Alıcı, Esma Hande; Arabacı, Gülnur (ELSEVIER, 2018)

In this study, a protease enzyme was purified from strawberry by using Sepharose-4B-L-tyrosine-p-amino benzoic acid affinity chromatography. The molecular weight of pure protease was determined 65.8 kDa by SDS-PAGE. The ...
