Aqueous extracts of seeds of Duranta plumieri were found to be rich in polyphenol oxidase activity. The anion-exchange chromatography of the crude extract on Streamline DEAE resolved the activity into three fractions. The major fraction (77% of the total activity) was further purified by treating it with concanavalin A-agarose in the batch mode. The enzyme preparation eluting with α-methylmannoside...
The double-headed inhibitor of α-amylase and Proteinase K was purified from wheat germ using Cu(II)-StreamlineTM-chelating resin. The endogenous α-amylase could be inactivated by heating. Followed by this step, both packed bed and expanded bed gave similar activity yield of around 83% and fold purification around 23. In the case of expanded bed, it was not necessary to separate precipitated protein...
