Protein Overview: Undecaprenyl phosphate-alpha-4-amino-4-deoxy-L-arabinose arabinosyl transferase

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.

Synonyms: 4-amino-4-deoxy-L-arabinose lipid A transferase, Lipid IV(A) 4-amino-4-deoxy-L-arabinosyltransferase, Undecaprenyl phosphate-alpha-L-Ara4N transferase

Gene name: arnT
