THERMOSTABLE ENZYME HAVING PHOSPHATE GROUP INTERMOLECULAR TRANSFER ACTIVITY IN SUGAR PHOSPHATE COMPOUND

摘要

PROBLEM TO BE SOLVED: To obtain a thermostable enzyme having phosphate group intermolecular transfer activity in a sugar phosphate compound and to stably produce a sugar phosphate to be a substrate for sugar chain synthesis.

SOLUTION: The gene of phosphate group intermolecular transferase in a sugar phosphate compound is found from all genome genetic information of Sulforobus tokodaii, superthermophilic archaebacterium and a thermostable phosphate group intermolecular transferase in a sugar phosphate compound is obtained by using the gene by an genetic engineering means. A sugar phosphate is stably produced by using the transferase.
