This domain is found in 3-Deoxy-d-arabino-heptulosonate-7-phosphate synthase (DAHPS) present in Thermotoga maritime. DAHPS catalyzes the first reaction of the aromatic biosynthetic pathway in bacteria, fungi, and plants, the condensation of PEP and E4P with the formation of DAHP. The domain is ferredoxin-like and is thought to play a critical role in feedback regulation of the enzyme [1].	Domain

Members of this family catalyse the first step in aromatic amino acid biosynthesis from chorismate. E-coli has three related synthetases, which are inhibited by different aromatic amino acids. This family also includes KDSA which has very similar catalytic activity but is involved in the first step of liposaccharide biosynthesis. The enzyme is also part of the shikimate pathway, EC:2.5.1.54.	Domain
