Sucrose phosphorylase (E.C. 184.108.40.206) is an important enzyme in the metabolism of sucrose and regulation of other metabolic intermediates. Sucrose phosphorylase is in the class of hexosyltransferases. More specifically it has been placed in the retaining glycoside hydrolases family although it catalyzes a transglycosidation rather than hydrolysis. Sucrose phosphorylase catalyzes the conversion of sucrose to D-fructose and α-D-glucose-1-phosphate. It has been shown in multiple experiments that the enzyme catalyzes this conversion by a double displacement mechanism.
Sucrose Phosphorylase, Recombinant
Sucrose phosphorylase has been used in a study to assess the enzymatic synthesis of stable, odorless, and powdered furanone glucosides. Sucrose phosphorylase has also been used in a study to investigate the novel transglucosylating reaction with carboxylic compounds.
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.
