A method for producing glycoconjugate, which comprises the steps of:
(i) binding a sugar residue to the side chain of a water-soluble polymer via a linker having a selectively cleavable linkage to give a primer, and bringing said primer into contact with an immobilized glycosyltransferase in the presence of a sugar nucleotide, to transfer a sugar residue of said sugar nucleotide to the sugar residue of said primer,
(ii) elongating a sugar chain by transfer of plural sugar residues by repeating the step (i) at least once,
(iii) removing, where necessary, a by-produced nucleotide or an unreacted sugar nucleotide, and
(iv) repeating the steps (i)-(iii) where necessary and releasing the glycoconjugate by selectively cleaving the cleavable linkage in the linker, from the above-mentioned primer connecting the sugar chain elongated by the transfer of plural sugar residues,
and a method for producing a sphingoglycolipid.
一种生产糖共轭物的方法,包括以下步骤
(i) 通过具有选择性可裂解连接的连接体,将糖残基与水溶性聚合物的侧链结合,得到引物,并在糖核苷酸存在的情况下,使所述引物与固定的糖基转移酶接触,将所述糖核苷酸的糖残基转移到所述引物的糖残基上、
(ii) 重复步骤(i)至少一次,通过转移多个糖残基拉长糖链、
(iii) 必要时去除副产核苷酸或未反应的糖核苷酸,以及
(iv) 必要时重复步骤(i)-(iii),通过选择性地裂解连接体中的可裂解连接,从上述连接通过转移多个糖残基拉长的糖链的引物中释放出糖共轭物、
以及一种生产鞘氨醇糖脂的方法。
