G2 — Sorghum bicolor

Summary

SORBI_3010G107200, also known as SbG2, encodes a 3-ketoacyl-CoA synthase, a member of the FAE1-type polyketide synthase family. The gene is associated with multiple acyltransferase activities, including naringenin-chalcone synthase and acridone synthase activities, and is linked to the biosynthesis of flavonoids, anthocyanins, waxes, and fatty acids. SbG2 has been connected to pigmentation, UV protection, and nitrogen fixation processes. The encoded protein localizes to the endoplasmic reticulum and membrane. Studies of related genes in other species link the broader gene family to additional polyketide synthase activities (EC 2.3.1.74, 2.3.1.151, 2.3.1.159, 2.3.1.199, 2.3.1.220).
