Arabinose 5-phosphate isomerase KdsD

UniProtKB accession:  P45395

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Involved in the biosynthesis of 3-deoxy-D-manno-octulosonate (KDO), a unique 8-carbon sugar component of lipopolysaccharides (LPSs). KdsD is not essential in the KDO biosynthesis and can be substituted by GutQ. Catalyzes the reversible aldol-ketol isomerization between D-ribulose 5-phosphate (Ru5P) and D-arabinose 5-phosphate (A5P).
