G2 — Sorghum bicolor

Summary

SORBI_3009G241000, also known as SbG2, encodes a 3-ketoacyl-CoA synthase with naringenin-chalcone synthase activity (EC 2.3.1.199) and belongs to the FAE1-type polyketide synthase family. The gene is associated with wax, fatty acid, flavonoid, anthocyanin, and polyketide biosynthesis, as well as pigmentation, UV protection, nitrogen fixation, and nitric oxide storage. Its product localizes to the membrane and exhibits acyltransferase and protein homodimerization activities. Studies of related genes in other species, such as CHS3 and 2PS, link the family to chalcone synthase activity (EC 2.3.1.74).
