General description
研究领域：细胞信号传导
蔗糖磷酸化酶属于糖苷水解酶GH13家族。它由四个结构域组成，包括葡萄糖异头碳结合位点和糖苷结合位点。活性位点残基包括Asp192和Glu232。它主要由双歧杆菌和乳酸杆菌产生。交联的蔗糖磷酸化酶聚集体具有热稳定性，可用于工业糖基化催化。

Application
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。
Biochem/physiol Actions
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)
Physical form
含有作为稳定剂的蔗糖。
Other Notes
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。

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

Replacements of Asp-295 by Asn (D295N) and Glu (D295E) decreased the catalytic center activity of Leuconostoc mesenteroides sucrose phosphorylase to about 0.01% of the wild-type level (k(cat)=200s(-1)). Glucosylation and deglucosylation steps of D295N were affected uniformly, approximately 10(4.3)-fold, and independently

Beta-D-Galactopyranosyl-(1-->3)-2-acetamido-2-deoxy-D-galactose (galacto-N-biose, GNB) is an important core structure in functional sugar chains such as T-antigen disaccharide and the core 1 sugar chain in mucin glycoproteins. We successfully developed a one-pot enzymatic production of GNB from sucrose and GalNAc by the

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
