UDP-3-O-acyl-N-acetylglucosamine deacetylase

UDP-3-O-acyl-N-acetylglucosamine deacetylase (EC 3.5.1.108), also known as LpxC, is a zinc-dependent enzyme involved in bacterial lipid A biosynthesis, catalyzing the removal of the acetyl group from UDP-3-O-acyl-N-acetylglucosamine, a key step in the production of lipopolysaccharides in the outer membrane of gram-negative bacteria.[1][2][3][4][5][6]

This enzyme catalyses the chemical reaction:

UDP-3-O-[(3R)-3-hydroxymyristoyl]-N-acetylglucosamine + H2O UDP-3-O-[(3R)-3-hydroxymyristoyl]-D-glucosamine + acetate

Nomenclature

edit

UDP-3-O-acyl-N-acetylglucosamine deacetylase is also known as:

  • UDP-3-O-((3R)-3-hydroxymyristoyl)-N-acetylglucosamine amidohydrolase
  • LpxC enzyme
  • LpxC deacetylase
  • deacetylase LpxC
  • UDP-3-O-acyl-GlcNAc deacetylase
  • UDP-3-O-((R)-3-hydroxymyristoyl)-N-acetylglucosamine deacetylase
  • UDP-(3-O-acyl)-N-acetylglucosamine deacetylase
  • UDP-3-O-(R-3-hydroxymyristoyl)-N-acetylglucosamine deacetylase
  • UDP-(3-O-(R-3-hydroxymyristoyl))-N-acetylglucosamine deacetylase)

Inhibitors

edit

Various inhibitors of LpxC have been developed as potential antibiotics, though none have yet reached clinical trials.[7][8][9]
