应用
蔗糖磷酸化酶已用于测定小麦植株中的蔗糖 和蔗糖氢的生产。
蔗糖磷酸化酶已用于：
- 评估稳定、无味且呈粉末状的呋喃酮糖苷的酶促合成。
- 研究与羧酸化合物的新型转糖基化反应。
- 用于小麦植株中的蔗糖测定和蔗糖制氢。
生化/生理作用
蔗糖磷酸化酶催化蔗糖（α-D-吡喃葡萄糖基-1,2-β-D-呋喃果糖苷）的可逆转化和将磷酸盐催化成D-果糖和α-D-葡萄糖1-磷酸。此反应在通过蔗糖代谢产生至关重要的葡萄糖组分方面起着关键作用。(1)
单位定义
在 25°C和pH 7.6下，一个单位每分钟将从蔗糖产生 1.0μ摩尔 D 果糖，同时相应地将NADP还原为NADPH。
外形
含有作为稳定剂的蔗糖。

Cellobiose phosphorylase from Clostridium thermocellum catalyzed the beta-anomer-selective synthesis of alkyl glucosides from cellobiose. Synthesis of alkyl beta-glucoside from inexpensive sucrose using cellobiose phosphorylase and sucrose phosphorylase from Pseudomonas saccharophilia was investigated. By combined use of these two phosphorylases, alkyl

We examined the synthesis of benzoyl glucoside using the transglucosylation reaction of sucrose phosphorylase. Sucrose phosphorylase from Streptococcus mutans showed marked transglucosylating activity, particularly under acidic conditions. On the other hand, sucrose phosphorylase from Leuconostoc mesenteroides showed very weak transglucosylating

The role of acid-base catalysis in the two-step enzymatic mechanism of alpha-retaining glucosyl transfer by Leuconostoc mesenteroides sucrose phosphorylase has been examined through site-directed replacement of the putative catalytic Glu237 and detailed comparison of purified wild-type and Glu237-->Gln mutant enzymes

Transglucosylation from sucrose to acetic acid by sucrose phosphorylase (EC 2.4.1.7) was studied. 1-O-Acetyl-alpha-D-glucopyranose was isolated as the main product of the enzyme reaction. We also compared the pH-dependence of transglycosylation catalyzed by sucrose phosphorylase toward carboxyl and hydroxyl groups.
