Description
The enzyme adds one or two ethanolamine phosphate groups to lipid A giving a diphosphate, sometimes in combination with EC 2.4.2.43 (lipid IVA 4-amino-4-deoxy-L-arabinosyltransferase) giving products with 4-amino-4-deoxy-β-L-arabinose groups at the phosphates of lipid A instead of diphosphoethanolamine groups. It will also act on lipid IVA and Kdo2-lipid A.
Form
Liquid or lyophilized powder
Storage
Store it at +4 ºC for short term. For long term storage, store it at -20 ºC～-80 ºC.
Synonyms
lipid A PEA transferase; PmrA; LptA
Reaction
(1) diacylphosphatidylethanolamine + lipid A = diacylglycerol + lipid A 1-(2-aminoethyl diphosphate); (2) diacylphosphatidylethanolamine + lipid A = diacylglycerol + lipid A 4'-(2-aminoethyl diphosphate); (3) diacylphosphatidylethanolamine + lipid A 1-(2-aminoethyl diphosphate) = diacylglycerol + lipid A 1,4'-bis(2-aminoethyl diphosphate)
