The main acceptor product of glucansucrases with d-mannose has not previously been identified. We used glucansucrases that form water-insoluble α-d-glucans to produce increased yields of acceptor products from d-mannose, and identified the major product as 6-O-α-d-glucopyranosyl-d-mannose. Glucansucrases that synthesize insoluble α-d-glucans produced higher yields of the disaccharide compared to typical dextransucrases.
具有 d-甘露糖的葡聚糖蔗糖酶的主要接受产物以前尚未被鉴定。我们使用形成不溶于水的α-d-葡聚糖的葡聚糖蔗糖酶来增加 d-甘露糖的接受产物的产量，并将主要产物鉴定为 6-O-α-d-吡喃葡萄糖基-d-甘露糖。与典型的右旋糖酐蔗糖酶相比，合成不溶性α-d-葡聚糖的葡聚糖蔗糖酶产生更高产量的二糖。
