General description
Research area: Cell signaling
Sucrose Phosphorylase belongs to glycoside hydrolase, GH13 family. It comprises of four domains with the glucose anomeric carbon-binding site and a glucoside-binding site. The active site residues include Asp192 and Glu232. It is majorly produced by bifidobacteria and lactic acid bacteria. The cross-linked sucrose phosphorylase aggregates is thermostable and could be exploited for industrial catalysis of glycosylation.

Application
Sucrose Phosphorylase has been used in sucrose determination in wheat plant and in sucrose hydrogen production.
Sucrose phosphorylase has been used:
- To assess the enzymatic synthesis of stable, odorless, and powdered furanone glucosides.
- To investigate the novel transglucosylating reaction with carboxylic compounds.
- In sucrose determination in wheat plant and in sucrose hydrogen production.
Biochem/physiol Actions
Sucrose phosphorylase catalyzes the reversible conversion of sucrose (α-D-glucopyranosyl-1,2-β-D-fructofuranoside) and phosphate into D-fructose and α-D-glucose 1-phosphate. This reaction plays a crucial role in generating the vital glucose component through sucrose metabolism.(1)
Unit Definition
One unit will produce 1.0 μmole of D-fructose from sucrose per min with the corresponding reduction of NADP to NADPH at pH 7.6, at 25 °C.
Physical form
Contains sucrose as stabilizer.

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.

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

The gene encoding sucrose phosphorylase (742sp) in Leuconostoc mesenteroides NRRL B-742 was cloned and expressed in Escherichia coli. The nucleotide sequence of the transformed 742sp comprised an ORF of 1,458 bp giving a protein with calculated molecular mass of 55.3

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
