Application

D-Arabinose 5-phosphate (D-Ara-5P) is used as a substrate to identify, differentiate and characterize enzymes such as D-arabinose 5-phosphate isomerase (KdsD) and 3-deoxy-D-manno-octulosonate 8-phosphate synthase(s) which are involved in lipopolysaccharide (LPS) biosynthesis.

A gene encoding for arabinose 5-phosphate isomerase (API), which catalyzes the interconversion of d-ribulose 5-phosphate (Ru5P) and d-arabinose 5-phosphate (A5P), has been identified from the genome of Escherichia coli K-12. API is the first enzyme in the biosynthesis of 3-deoxy-d-manno-octulosonate

We explored the D-arabinose 5-phosphate isomerase (KdsD, E.C. 5.3.1.13) from Francisella tularensis, a highly infectious gram-negative pathogen that has raised concern as a potential bioweapon, as a target for the development of novel chemotherapeutics. F. tularensis KdsD was expressed in

3-Deoxy-D-manno-octulosonate 8-phosphate synthase (KDO8PS) catalyzes the reaction between three-carbon phosphoenolpyruvate (PEP) and five-carbon d-arabinose 5-phosphate (A5P), generating KDO8P, a key intermediate in the biosynthetic pathway to 3-deoxy-D-manno-octulosonate, a component of the lipopolysaccharide of the Gram-negative bacterial cell wall. Both metal-dependent

Lipopolysaccharide (LPS) biosynthesis represents an underexploited target pathway for novel antimicrobial development to combat the emergence of multidrug-resistant bacteria. A key player in LPS synthesis is the enzyme D-arabinose-5-phosphate isomerase (API), which catalyzes the reversible isomerization of D-ribulose-5-phosphate to D-arabinose-5-phosphate
