1,4-beta-D-xylan synthase

Class of enzymes March 2020 1,4-beta-D-xylan synthase 2.4.2.24 37277-73-9 0047517 In enzymology, a 1,4-beta-D-xylan synthase (2.4.2.24) is an enzyme that catalyzes the chemical reaction UDP-D-xylose + (1,4-beta-D-xylan)n UDP + (1,4-beta-D-xylan)n+1 Thus, the two substrates of this enzyme are UDP-D-xylose and (1,4-beta-D-xylan)n, whereas its two products are UDP and (1,4-beta-D-xylan)n+1. This enzyme belongs to the family of glycosyltransferases, specifically the pentosyltransferases. The systematic name of this enzyme class is UDP-D-xylose:1,4-beta-D-xylan 4-beta-D-xylosyltransferase. Other names in common use include uridine diphosphoxylose-1,4-beta-xylan xylosyltransferase, 1,4-beta-xylan synthase, xylan synthase, and xylan synthetase. This enzyme participates in starch and sucrose metabolism and nucleotide sugars metabolism.
