ACS — Triticum turgidum subsp. durum

Summary

TRITD5AV1G197200 (symbol ACS, preferred name TtACS) on durum wheat chromosome 5A encodes a 4-coumarate–CoA ligase, a member of the AMP-binding enzyme superfamily. The gene product exhibits multiple CoA ligase activities, including 4-coumarate-CoA ligase, acetate-CoA ligase, and long-chain acyl-CoA synthetase activities (EC 6.2.1.12). It is associated with phenylpropanoid metabolism, fatty-acyl-CoA anabolism, cinnamic acid metabolism, phytoalexin biosynthesis, and green leaf volatile biosynthesis. The protein localises to the endoplasmic reticulum and cytosol. TtACS is linked to responses to jasmonic acid, ethylene, wounding, and circadian rhythm, and is associated with stripe rust. Related genes in other species further associate this gene family with diverse CoA ligase activities (EC 6.2.1.1, 6.2.1.17, 6.2.1.78, 6.2.1.34).
