{{Short description|Class of enzymes}} {{infobox enzyme | Name = dextransucrase | EC_number = 2.4.1.5 | CAS_number = 9032-14-8 | GO_code = 0047849 | image = | width = | caption = }} In enzymology, a '''dextransucrase''' ({{EC number|2.4.1.5}}) is an enzyme that catalyzes the chemical reaction
:sucrose + (1,6-alpha-D-glucosyl)<sub>n</sub> <math>\rightleftharpoons</math> D-fructose + (1,6-alpha-D-glucosyl)<sub>n+1</sub>
Thus, the two substrates of this enzyme are sucrose and (1,6-alpha-D-glucosyl)<sub>n</sub>, whereas its two products are D-fructose and (1,6-alpha-D-glucosyl)<sub>n+1</sub>.
This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is '''sucrose:1,6-alpha-D-glucan 6-alpha-D-glucosyltransferase'''. Other names in common use include '''sucrose 6-glucosyltransferase''', '''SGE''', '''CEP''', and '''sucrose-1,6-alpha-glucan glucosyltransferase'''. This enzyme participates in starch and sucrose metabolism and two-component system - general.
