Identification
Name: Undecaprenyl phosphate-alpha-4-amino-4-deoxy-L-arabinose arabinosyl transferase
Synonyms:
  • 4-amino-4-deoxy-L-arabinose lipid A transferase
  • Polymyxin resistance protein pmrK
  • Undecaprenyl phosphate-alpha-L-Ara4N transferase
Gene Name: arnT
Enzyme Class:
Biological Properties
General Function: Involved in transferase activity, transferring pentosyl groups
Specific Function: Catalyzes the transfer of the L-Ara4N moiety of the glycolipid undecaprenyl phosphate-alpha-L-Ara4N to lipid A. The modified arabinose is attached to lipid A and is required for resistance to polymyxin and cationic antimicrobial peptides
Cellular Location: Cell inner membrane; Multi-pass membrane protein
KEGG Pathways:
  • Cationic antimicrobial peptide (CAMP) resistance pae01503
