In enzymology, a glucomannan 4-beta-mannosyltransferase (EC 2.4.1.32) is an enzyme that catalyzes the chemical reaction
- GDP-mannose + (glucomannan)n GDP + (glucomannan)n+1
Thus, the two substrates of this enzyme are GDP-mannose and (glucomannan)n, whereas its two products are GDP and (glucomannan)n+1.
This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is GDPmannose:glucomannan 1,4-beta-D-mannosyltransferase. Other names in common use include GDP-man-beta-mannan manosyltransferase, and glucomannan-synthase.
