Identification
Name:UDP-3-O-[3-hydroxymyristoyl] N-acetylglucosamine deacetylase
Synonyms:
  • Protein envA
  • UDP-3-O-acyl-GlcNAc deacetylase
Gene Name:lpxC
Enzyme Class:
Biological Properties
General Function:Involved in UDP-3-O-[3-hydroxymyristoyl] N-acetylglucosamine deacetylase activity
Specific Function:The key enzyme in the biosynthesis of lipid A, a phosphorylated glycolipid that anchors the lipopolysaccharide to the outer membrane of the cell. Degraded by FtsH; when the activity of FtsH is reduced too much lipid A and not enough phospholipids are made (both pathways use the same precursor), which is lethal
