Levansucrase

Levansucrase (EC 2.4.1.10) is an enzyme that catalyzes the chemical reaction Levansucrase (EC 2.4.1.10) is an enzyme that catalyzes the chemical reaction 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. The systematic name of this enzyme class is sucrose:2,6-beta-D-fructan 6-beta-D-fructosyltransferase. Other names in common use include sucrose 6-fructosyltransferase, beta-2,6-fructosyltransferase, and beta-2,6-fructan:D-glucose 1-fructosyltransferase. This enzyme participates in starch and sucrose metabolism and two-component system - general. As of late 2007, 3 structures have been solved for this class of enzymes, with PDB accession codes 1OYG, 1PT2, and 1W18.
