Descrição geral
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.

Aplicação
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.
Ações bioquímicas/fisiológicas
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)
Definição da unidade
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.

Sucrose phosphorylase utilizes a glycoside hydrolase-like double displacement mechanism to convert its disaccharide substrate and phosphate into alpha-d-glucose 1-phosphate and fructose. Site-directed mutagenesis was employed to characterize the proposed roles of Asp(196) and Glu(237) as catalytic nucleophile and acid-base, respectively
