UDP-2,3-diacylglucosamine diphosphatase (EC 3.6.1.54, UDP-2,3-diacylglucosamine hydrolase, UDP-2,3-diacylglucosamine pyrophosphatase, ybbF (gene), lpxH (gene)) is an enzyme with systematic name UDP-2,3-bis((3R)-3-hydroxymyristoyl)-alpha-D-glucosamine 2,3-bis((3R)-3-hydroxymyristoyl)-beta-D-glucosaminyl 1-phosphate phosphohydrolase.[1][2] This enzyme catalyses the following chemical reaction

UDP-2,3-bis[(3R)-3-hydroxymyristoyl]-alpha-D-glucosamine + H2O [math]\displaystyle{ \rightleftharpoons }[/math] 2,3-bis[(3R)-3-hydroxymyristoyl]-beta-D-glucosaminyl 1-phosphate + UMP

The enzyme catalyses a step in the biosynthesis of lipid A.
