ASA2 — Brassica oleracea var. botrytis

Summary

BoASA2 (ASA2) on cauliflower chromosome 3 encodes a protein with aminodeoxychorismate synthase activity and anthranilate synthase activity, and also has domains associated with DNA replication origin binding and ATP hydrolysis. The gene is associated with tryptophan formation, folate biosynthesis, the S-M checkpoint, response to sucrose, and cell division. It localises to the anthranilate synthase complex, the nuclear origin recognition complex, the cytoplasm, and the nucleus. Related genes in other species link the family to anthranilate synthase activity (EC 4.1.3.27) and aminodeoxychorismate synthase activity (EC 2.6.1.85), and have been associated with photochemical quenching.
