DE   lipid IVA 4-amino-4-deoxy-L-arabinosyltransferase.
AN   4-amino-4-deoxy-L-arabinose lipid A transferase.
AN   lipid A 4-amino-4-deoxy-L-arabinosyltransferase.
AN   polymyxin resistance protein PmrK.
AN   undecaprenyl phosphate-alpha-4-amino-4-deoxy-L-arabinose arabinosyl
AN   transferase.
AN   undecaprenyl phosphate-alpha-L-Ara4N transferase.
CA   4-amino-4-deoxy-alpha-L-arabinopyranosyl di-trans,octa-cis-undecaprenyl
CA   phosphate + lipid IVA = lipid IIA + di-trans,octa-cis-undecaprenyl
CA   phosphate.
CC   -!- Integral membrane protein present in the inner membrane of certain
CC       Gram negative endobacteria.
CC   -!- In strains that do not produce 3-deoxy-D-manno-octulosonic acid
CC       (Kdo), the enzyme adds a single arabinose unit to the 1-phosphate
CC       moiety of the tetra-acylated lipid A precursor, lipid IVA.
CC   -!- In the presence of a Kdo disaccharide, the enzyme primarily adds an
CC       arabinose unit to the 4-phosphate of lipid A molecules.
CC   -!- The Salmonella typhimurium enzyme can add arabinose units to both
CC       positions.
CC   -!- Formerly EC 2.4.2.n1.
