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 |
