摘要
Dear Editor,O-GIcNAcylation is a nutrient sensor that is particularly sensitive to environmental glucose(Hardiville and Hart,2014).Glucose can be converted to UDP-GIcNAc through the hexosamine biosynthetic pathway,providing a substrate for O-GIcNAcylation.Two enzymes participate in this reversible modification,O-GIcNAc transferase(OGT),which adds a single GIcNAc residue to the serine/threonine sites of proteins,and O-GIcNAcase(OGA),which removes the residue(Yang and Qian,2017).
