Common Name2-Dehydro-3-deoxy-D-arabino-heptonate 7-phosphate
Description2-dehydro-3-deoxy-D-arabino-heptonate 7-phosphate is a member of the chemical class known as Medium-chain Keto Acids and Derivatives. These are keto acids with a 6 to 12 carbon atoms long side chain. DAHPS is involved in the biosynthesis of aromatic amino acids. Maritima DAHP synthase is a metalloenzyme. This report is the first description of a thermophilic eubacterial DAHP synthase. (PMID 12743122 ) DAHPS(Phe) is a metal-catalyzed oxidation system wherein bound substrate protects active-site residues from oxidative attack catalyzed by bound redox metal cofactor. (PMID 10049398 ) The first regulatory step in the synthesis of aromatic amino acids is catalyzed by 3-deoxy-D-arabino-heptulosonate 7-phosphate synthase (DAHPS). (PMID 15378531 ) While several similarities exist between the two enzymatic reactions, classic studies on the Escherichia coli enzymes have established that DAHPS is a metalloenzyme, whereas KDO8PS has no metal requirement. aeolicus KDO8PS is a metalloenzyme in vivo and point to a previously unrecognized relationship between the KDO8PS and DAHPS families.
