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.

Biological Context

Subcellular Location: Cell inner membrane (Multi-pass membrane protein)
Pathway: Lipopolysaccharide metabolism; 4-amino-4-deoxy-beta-L-arabinose-lipid A biosynthesis

Product Specifications

Recombinant Klebsiella pneumoniae Undecaprenyl phosphate-alpha-4-amino-4-deoxy-L-arabinose arabinosyl transferase (arnT), partial is a recombinant protein from Klebsiella pneumoniae (strain 342), expressed in E.coli, covering amino acids 429-551aa, with N-terminal 6xHis-tagged tag, molecular weight 17.8kDa, purity Greater than 90% as determined by SDS-PAGE.. Suitable for ELISA and Western Blot applications.

SDS-PAGE: Single band at expected molecular weight confirming purity.
