G2 — Sorghum bicolor

Summary

SORBI_3010G108301, designated SbG2 on sorghum chromosome 10, encodes a 3-ketoacyl-CoA synthase, a member of the FAE1-type polyketide synthase family with acyltransferase activity (EC 2.3.1.-). The gene is associated with multiple metabolic pathways, including wax, anthocyanin, and fatty acid anabolism, as well as malonyl-CoA and benzoyl-CoA metabolism. It is linked to pigmentation, UV protection, and nitrogen fixation processes, and its product localizes to membranes. Related genes in other species connect this group to very-long-chain fatty acid elongation and cuticular wax biosynthesis. The gene is also associated with polyketide anabolism and nitric oxide storage.
