Abstract |
UDP-apiose, a donor substrate of apiosyltransferases, is labile because of its intramolecular self-cyclization ability, resulting in the formation of apiofuranosyl-1,2-cyclic phosphate. Therefore, stabilization of UDP-apiose is indispensable for its availability and identifying and characterizing the apiosyltransferases involved in the biosynthesis of apiosylated sugar chains and glycosides. Here, we established a method for stabilizing UDP-apiose using bulky cations as counter ions. Bulky cations such as triethylamine effectively suppressed the degradation of UDP-apiose in solution. The half-life of UDP-apiose was increased to 48.1 ± 2.4 h at pH 6.0 and 25 °C using triethylamine as a counter cation. UDP-apiose coordinated with a counter cation enabled long-term storage under freezing conditions. UDP-apiose was utilized as a donor substrate for apigenin 7-O-β-D-glucoside apiosyltransferase to produce the apiosylated glycoside apiin. This apiosyltransferase assay will be useful for identifying genes encoding apiosyltransferases.
