    摘要: Fructosylated puerarin being converted from puerarin by a bioconversion method conducted in an aqueous phase or nonaqueous phase system, including monofructosyl-(2,6)-puerarin, bifructosyl-(2,6)-puerarin, trifructosyl-(2,6)-puerarin, tetrafructosyl-(2,6)-puerarin and pentafructosyl-(2,6)-puerarin. Tests have shown that the oligosaccharylated puerarin is effective to treat acute myocardial ischemia, and can markedly suppress in vitro the proliferation of human breast cancer cell strain MDA-MB-23 and human chronmyelogenors leukemia cell strain K562, and it has a low toxicity.

    摘要: The object of the present invention is to provide &agr;1,4-galactosyltransferase to transfer a galactose residue to C4 position of galactose residue of lactosylceramide or galactosylceramide, and DNA coding for the enzyme. What is provided includes the following polypeptides (a) and (b), and DNAs encoding thereof: (a) a polypeptide consisting of an amino acid sequence represented by the amino acid Nos. 46-353 in SEQ ID NO: 2; or (b) a polypeptide which comprises an amino acid sequence including substitution, deletion, insertion or transposition of one or few amino acids in the amino acid sequence of (a) and which has an enzymatic activity to transfer a galactose residue from a galactose donor to C4 position of galactose residue of lactosylceramide or galactosylceramide which serves as an acceptor.
