DQD1 — Aspergillus nidulans FGSC A4

Summary

ANIA_01135 (DQD1, AnDQD1) on Aspergillus nidulans chromosome 8 encodes a type II dehydroquinase, confirmed by its 3-dehydroquinate dehydratase activity (EC 4.2.1.10) and the DHquinase_II domain family. The gene is associated with the shikimate pathway, quinate breakdown, and protocatechuate anabolism. Sequence-similarity links to related genes in other species place the family in quinate and shikimate metabolism, and these connections also associate DQD1 with amino acid content. The family has been linked to the plant pathogens Verticillium dahliae and Fusarium oxysporum, though these associations are not established for A. nidulans itself.
