CC   -!- FUNCTION: Catalyzes the transfer of the L-Ara4N moiety of the
CC       glycolipid undecaprenyl phosphate-alpha-L-Ara4N to lipid A. The
CC       modified arabinose is attached to lipid A and is required for
CC       resistance to polymyxin and cationic antimicrobial peptides.
CC       {ECO:0000255|HAMAP-Rule:MF_01165}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=4-amino-4-deoxy-alpha-L-arabinopyranosyl di-trans,octa-cis-
CC         undecaprenyl phosphate + lipid IVA = lipid IIA + di-trans,octa-cis-
CC         undecaprenyl phosphate.; EC=2.4.2.43; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_01165};
CC   -!- PATHWAY: Lipopolysaccharide metabolism; 4-amino-4-deoxy-beta-L-
CC       arabinose-lipid A biosynthesis. {ECO:0000255|HAMAP-Rule:MF_01165}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_01165}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_01165}.
CC   -!- SIMILARITY: Belongs to the glycosyltransferase 83 family.
CC       {ECO:0000255|HAMAP-Rule:MF_01165}.
