Research AreasBiochemicals

Function

Transfers the gamma-phosphate of ATP to the 4'-position of a tetraacyldisaccharide 1-phosphate intermediate (termed DS-1-P) to form tetraacyldisaccharide 1,4'-bis-phosphate (lipid IVA).

Biological Context

Pathway: Glycolipid biosynthesis; lipid IV(A) biosynthesis; lipid IV(A) from (3R)-3-hydroxytetradecanoyl-[acyl-carrier-protein] and UDP-N-acetyl-alpha-D-glucosamine: step 6/6

Product Specifications

Recombinant Escherichia coli Tetraacyldisaccharide 4-kinase (lpxK) is a recombinant protein from Escherichia coli (strain K12 / MC4100 / BW2952), expressed in E.coli, covering amino acids 1-328aa, with N-terminal 10xHis-tagged and C-terminal Myc-tagged tag, molecular weight 43.0kDa, purity Greater than 85% as determined by SDS-PAGE.. Suitable for ELISA and Western Blot applications.

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

ELISA: Suitable as coating antigen or detection standard.
