A process for the production of a glycoconjugate by N-glycosylation of a protein or peptide comprising the sequence D/E-X—N—X—S/T, wherein each X is the same or different and is any natural amino acid other than proline, wherein the process comprises reacting the protein or peptide with a polyisoprenyl pyrophosphate of formula (I), or a salt thereof, in the presence of PglB: (I) to produce the glycoconjugate comprising the protein or peptide having a saccharide [SI] linked to the asparagine in the sequence D/E-X—N—X—S/T. Polyisoprenylpyrophosphates used as substrates in the biocatalytic process are also provided, as well as certain glycoconjugates.
一种通过将具有序列D / E-X-N-X-S / T的蛋白质或肽N-糖基化来生产糖蛋白的方法,其中每个X相同或不同,是除脯氨酸以外的任何天然氨基酸,该过程包括在存在PglB的情况下,将蛋白质或肽与式(I)的多异戊烯基焦磷酸盐或其盐反应,以产生包含与序列D / E-X-N-X-S / T中的天冬氨酸连接的糖[SI]的蛋白质或肽的糖蛋白。还提供了用作生物催化过程中底物的多异戊烯基焦磷酸盐以及某些糖蛋白。
