Levansucrase

Levansucrase (EC 2.4.1.10) is an enzyme that catalyzes the chemical reaction: sucrose + (2,6-beta-D-fructosyl)n → glucose + (2,6-beta-D-fructosyl)n+1. Thus, the two substrates of this enzyme are sucrose and (2,6-beta-D-fructosyl)n, whereas its two products are glucose and (2,6-beta-D-fructosyl)n+1. This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases.
