Gene name	Name=arnT;

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 IVA = lipid IIA + 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.
