Abstract

The 3-dehydroquinate synthase (EC:4.6.1.3) domain is present in isolation in various bacterial 3-dehydroquinate synthases and also present as a domain in the pentafunctional AROM polypeptide (P07547) [1]. 3-dehydroquinate (DHQ) synthase catalyses the formation of dehydroquinate (DHQ) and orthophosphate from 3-deoxy-D-arabino heptulosonic 7 phosphate [2]. This reaction is part of the shikimate pathway which is involved in the biosynthesis of aromatic amino acids.
