产品介绍： SPY (SPINDLY) is O-linked N-acetylglucosamine transferase (OGT) involved in various processes such as gibberellin (GA) signaling pathway and circadian clock. It catalyze the addition of nucleotide-activated sugars directly onto the polypeptide through O-glycosidic linkage with the hydroxyl of serine or threonine. Acts as a repressor of GA signaling pathway to inhibit hypocotyl elongation. Alternative name: Probable UDP-N-acetylglucosamine--peptide N-acetylglucosaminyltransferase SPINDLY.
