ID   2.7.8.43
DE   lipid A phosphoethanolamine transferase.
AN   lipid A PEA transferase.
CA   (1) a 1,2-diacyl-sn-glycero-3-phosphoethanolamine + H(+) + lipid A (E.
CA   coli) = a 1,2-diacyl-sn-glycerol + lipid A hexaacyl 1-(2-aminoethyl
CA   diphosphate).
CA   (2) a 1,2-diacyl-sn-glycero-3-phosphoethanolamine + H(+) + lipid A (E.
CA   coli) = a 1,2-diacyl-sn-glycerol + lipid A 4'-(2-aminoethyl diphosphate)
CA   (E. coli).
CA   (3) a 1,2-diacyl-sn-glycero-3-phosphoethanolamine + H(+) + lipid A
CA   hexaacyl 1-(2-aminoethyl diphosphate) = a 1,2-diacyl-sn-glycerol + lipid
CA   A 1,4'-bis(2-aminoethyl diphosphate).
CC   -!- The enzyme adds one or two ethanolamine phosphate groups to lipid A
CC       giving a diphosphate, sometimes in combination with EC 2.4.2.43
CC       giving products with 4-amino-4-deoxy-beta-L-arabinose groups at the
CC       phosphates of lipid A instead of diphosphoethanolamine groups.
CC   -!- It will also act on lipid IVA and Kdo2-lipid A.
CC   -!- Formerly EC 2.7.4.30.
