Comments [?]

Function Catalyzes the transfer of the L-Ara4N moiety of the glycolipid undecaprenyl phosphate-alpha-L-Ara4N to lipid A. The modified arabinose is attached to lipid A and is required for resistance to polymyxin and cationic antimicrobial peptides.
Catalytic activity Reaction=4-amino-4-deoxy-alpha-L-arabinopyranosyl di-trans,octa-cis-undecaprenyl phosphate + lipid IV(A) = lipid II(A) + di-trans,octa-cis-undecaprenyl phosphate.; EC=2.4.2.43;
Pathway Lipopolysaccharide metabolism; 4-amino-4-deoxy-beta-L-arabinose-lipid A biosynthesis.
case not defined <Property:Membrane> or <Property:Membrane=1>
Subcellular location Cell membrane; Multi-pass membrane protein.
else case <Property:Membrane=2>
Subcellular location Cell inner membrane; Multi-pass membrane protein.
end case
Similarity Belongs to the glycosyltransferase 83 family.
