ACO — Pisum sativum

Summary

PSAT0S3098G0040 (symbol ACO) in garden pea (Pisum sativum, chromosome CAADHX020009187.1) encodes a protein with aconitase, aminopeptidase, and amino acid permease activities, containing aconitase and peptidase M18 domains and binding 4Fe-4S clusters, zinc, and other metals. The gene is associated with the TCA cycle, glyoxylate cycle, citrate and isocitrate metabolism, ethylene anabolism, auxin signaling, proteolysis, amino acid transport, cell growth, geotropism, nodulation, seed development, and seed germination. It is linked to membrane, mitochondrial, plasmalemma, and cytoplasmic localization. Associations with flower color, seed coat color, proline content, and salt tolerance have been noted. Studies of related genes in other species, including aconitate hydratase and aspartyl aminopeptidase, connect the family to aconitase (EC 4.2.1.3) and aminopeptidase (EC 3.4.11.21) activities.
