EC 2.4.1.12

Accepted name: cellulose synthase (UDP-forming)

Reaction: UDP-glucose + [(1→4)-β-D-glucosyl]n = UDP + [(1→4)-β-D-glucosyl]n+1

Other name(s): UDP-glucose—β-glucan glucosyltransferase; UDP-glucose-cellulose glucosyltransferase; GS-I; β-1,4-glucosyltransferase; uridine diphosphoglucose-1,4-β-glucan glucosyltransferase; β-1,4-glucan synthase; β-1,4-glucan synthetase; β-glucan synthase; 1,4-β-D-glucan synthase; 1,4-β-glucan synthase; glucan synthase; UDP-glucose-1,4-β-glucan glucosyltransferase; uridine diphosphoglucose-cellulose glucosyltransferase; UDP-glucose:1,4-β-D-glucan 4-β-D-glucosyltransferase

Systematic name: UDP-glucose:(1→4)-β-D-glucan 4-β-D-glucosyltransferase

Comments: Involved in the synthesis of cellulose. A similar enzyme utilizes GDP-glucose [EC 2.4.1.29 cellulose synthase (GDP-forming)].
