An object of the present invention is to provide a sugar donating reagent comprising a sugar donor compound other than a sugar nucleotide and an enzyme capable of catalyzing a glycosyl transfer reaction using a sugar donor compound other than a sugar nucleotide. The present invention provides the following: a sugar donating reagent containing a compound of formula (A):
wherein R
1
is independently selected from hydrogen, or C
1-6
alkyl, C
2-6
alkenyl, and C
2-6
alkynyl in which each of the groups is unsubstituted or substituted with one or more groups selected from OH, F, Cl, Br, I, CN, NO
2
, and SO
2
, n is 0, 1, 2, 3, 4 or 5, m is 0 or 1, and X represents a monosaccharide bound via a β bond on its anomeric carbon; a glycosyltransferase capable of catalyzing a glycosyl transfer reaction using the sugar donor; and a glycosyltransferase gene comprising DNA encoding the glycosyltransferase.
本发明的目的是提供一种含有糖供体化合物的糖供体试剂,该糖供体化合物不是糖核苷酸,并且包含一种能够催化使用糖供体化合物进行糖基转移反应的酶。本发明提供以下内容:一种糖供体试剂,其包含式(A)的化合物:其中R1独立地选自氢、C1-6烷基、C2-6烯基和C2-6炔基,其中每个基团未取代或取代有一种或多种从OH、F、Cl、Br、I、CN、NO2和SO2中选出的基团,n为0、1、2、3、4或5,m为0或1,X代表通过其环式异构碳上的β键结合的单糖;一种能够催化使用糖供体进行糖基转移反应的糖基转移酶;以及编码糖基转移酶的DNA的糖基转移酶基因。
