Chain A (LPXC_AQUAE | O67648)

molecular function
	GO:0008759	UDP-3-O-[3-hydroxymyristoyl] N-acetylglucosamine deacetylase activity	Catalysis of the removal of an acetyl group from the 2-N position of glucosamine in the lipid A precursor UDP-3-O-(R-3-hydroxymyristoyl)-N-acetylglucosamine.
	GO:0103117	UDP-3-O-acyl-N-acetylglucosamine deacetylase activity	Catalysis of the reaction: UDP-3-O-[(3R)-3-hydroxytetradecanoyl]-N-acetylglucosamine(2-) + H2O <=> UDP-3-O-[(3R)-3-hydroxytetradecanoyl]-alpha-D-glucosamine(1-) + acetate
	GO:0016787	hydrolase activity	Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
	GO:0046872	metal ion binding	Interacting selectively and non-covalently with any metal ion.
biological process
	GO:0009245	lipid A biosynthetic process	The chemical reactions and pathways resulting in the formation of lipid A, the glycolipid group of bacterial lipopolysaccharides, consisting of four to six fatty acyl chains linked to two glucosamine residues. Further modifications of the backbone are common.
	GO:0006629	lipid metabolic process	The chemical reactions and pathways involving lipids, compounds soluble in an organic solvent but not, or sparingly, in an aqueous solvent. Includes fatty acids; neutral fats, other fatty-acid esters, and soaps; long-chain (fatty) alcohols and waxes; sphingoids and other long-chain bases; glycolipids, phospholipids and sphingolipids; and carotenes, polyprenols, sterols, terpenes and other isoprenoids.
