General annotation (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. Ref.3

Catalytic activity

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. Ref.3

Pathway

Lipopolysaccharide metabolism; 4-amino-4-deoxy-beta-L-arabinose-lipid A biosynthesis. HAMAP-Rule MF_01165

Subcellular location

Cell inner membrane; Multi-pass membrane protein Ref.4.

Induction

Induced by BasR By similarity.

Sequence similarities

Belongs to the glycosyltransferase 83 family.
