研究了肠系膜白菌蔗糖磷酸化酶催化蔗糖转糖基化制曲酸的过程。得到了两种转移产物。通过二级离子质谱分析、酶解产物组分分析和碳-13核磁共振谱分析，分别鉴定为曲酸5-O-α-d-葡萄糖苷和曲酸7-O-α-d-葡萄糖苷。
Transglycosylation from sucrose to kojic acid by sucrose phosphorylase from Leuconostoc mesenteroides was studied. Two transfer products were obtained. These structures were identified as kojic acid 5-O-α-d-glucopyranoside and kojic acid 7-O-α-d-glucopyranoside on the bases of secondary ion mass spectrum analyses, the component analyses of their enzymatic hydrolyzates, and the carbon-13 nuclear magnetic resonance spectrum analyses.
