RL Submitted (NOV-2007) to the EMBL/GenBank/DDBJ databases.
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}.
