    An Arginine Specific Protease from Spirulina platensis

    An arginine specific protease, Sp-protease, was purified by column chromatography from freeze-dried Spirulina platensis using a five-step process. Purified Sp-protease has a molecular weight of 80 kDa. It hydroly...

    Regioselective deacetylation of peracetylated monosaccharide derivatives by polyethylene glycol-modified lipase for the oligosaccharide synthesis

    Lipase modified with polyethylene glycol became soluble and active in organic solvents, and catalyzed regioselective deacetylation of peracetylated monosaccharide derivatives in 1,1,1-trichloroethane. The deac...

    Ester synthesis from α-substituted carboxylic acid catalyzed by polyethylene glycol-modified lipase fromCandida cylindracea in benzene

    Lipase fromCandida cylindracea was coupled with polyethylene glycol(PEG). In contrast to the previously used lipase fromPseudomonas fluorescens, the modified lipase catalyzed the ester synthesis in benzene at 25°...
