UDP-glucose sterol glucosyltransferase (SGT) are enzymes typically involved in the production of sterol glycosides (SG) in various organisms. However, the biological functions of SGTs in plants remain largely unknown. In the present study, we identified two full-length GhSGT genes in cotton and examined their distinct biochemical properties. Using UDP-[U-(14)C]-glucose and β-sitosterol or total crude membrane sterols as substrates, GhSGT1 and GhSGT2 recombinant proteins were detected with… CONTINUE READING
