UDP-2,3-diacylglucosamine diphosphatase

UDP-2,3-diacylglucosamine diphosphatase (, 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. This enzyme catalyses the following chemical reaction


 * UDP-2,3-bis[(3R)-3-hydroxymyristoyl]-alpha-D-glucosamine + H2O $$\rightleftharpoons$$ 2,3-bis[(3R)-3-hydroxymyristoyl]-beta-D-glucosaminyl 1-phosphate + UMP

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